Ways to look handsome!One disclaimer before reading "Looking good is not age/weight/family specific." Now we can start off with understanding what does handsome means. Does it mean wearing good clothes? Or having a good face? Or having a good body? What is it actually? Well, a simple definition could be "being handsome means being confident and having loads of style and poise." It's not dependent on somebody's face or body specifically. So what makes a person handsome? Will his attitude count? Do we need a lot of money to get that look? Let's answer all such questions in the article. Personal care: The first and the foremost cornerstone for getting a perfect look is to look after yourself well. This includes- Hygiene - Personal hygiene is most important. Dental hygiene, managing body odor, cutting your nails on time, removing hair in the underarms, nose, and taking care of overall body hygiene is of utmost importance.Skin care - Taking care of one's skin is no more a girly thing now; men need to do the same as well. Applying moisturizers, lotions that are readily available, tailor-made for men.Hair care - Men do not need to spend a lot of time managing their hair as women do, but that doesn't mean they can get all complacent about them. Try and wash and shampoo your hair at least twice in a week. You could use natural or artificial conditioners in the hair to make it soft. Get a trim every month or else they can become too long to manage. The suave and debonair look, along with the above indicated personal care methods; one important pointer is to take care of one's facial hair. Agreed that the rough and rugged look is good with some clothes and skin colors, but try and avoid it as 'a regular' and get a good shave. You can either keep a clean shaven look or keep a beard which is well trimmed. This will give you an urbane and classy look. Clothes cabana - An important factor for your looks is your clothes as well. One needs to understand that there are particular kinds of clothes which shall look good on them and there is a section which they should never try. Once you understand this thin line, you can do wonders with your clothes. Try to understand which shades look good on you. The bright colors or pastel shades. After this, you need to choose your formal and casual wears as well. Try and understand what kind of clothes make you look good and what are the options you can always try. The must have checklist is given below - A pair of good dark blue jeans. A white shirt. A colored T-shirt. Jacket and waist coat. Dinner jacket or tuxedo (whichever suits you). Pair of black trousers. Sweatshirts. A full pastel shade sweater. Accessorize your look - Along with good clothes you need a few more embellishments:Shoes - Get two different pairs - one leather and the other sports for formal and informal occasions. The shoes should be buffed with shoe wax regularly and you can wash off the dirt on your sports shoes once every couple of weeks.Belts and Tie - A good and well-fitting tie and a sober choice in belts always adds to the look of the "complete man."Watches - A good analog watch is a "must have" on every guy's wrist for that added attraction. Work out regimens - Now workout does not only mean joining a gym or keeping a personal trainer. You need to just keep your body fit, which can be done by jogging, yoga, or even a morning and evening walk. Try to be active, which in turn will help you stay in shape. You can even pick up a sport for that matter. When your body is fit, you will have a relaxed mind and soul too. Eat healthy - Having a hamburger everyday will make you only lethargic and fat and certainly far from handsome. Try to follow a diet regimen which nowhere means you need to have nightmarish boiled vegetables only. You just need to avoid eating outside which means no junk or oily food. This shall not only help you look good, but will let you be young and fit. Try to have more leafy vegetables and fish in your daily diet rather than red meat and spices. Once in a week you can dig into your favorite foods and pig out. Say no to cigarettes and alcohol - Working out or eating healthy and getting the best clothes and accessories will never help you get in good shape until you say no to all the habits which shall prove deadly for you in the future. Try and quit smoking and drinking as they affect your health and stamina in the most adverse ways possible. Along with that they also have a very bad effect on your mental health as they become an addiction and hamper your concentration and thinking abilities as well. Million dollar smile - Wearing good clothes do not have a prerequisite of behaving like a supermodel anywhere. Try to wear a good and sweet smile which shall give you a nice and attractive look at the same time. A straight face might end up making you look unapproachable and arrogant, so remember smiling always to complete your attire and style. Good stance - Wearing all the best outfits and looking a million bucks might go all in vain if you have a bad body posture. Try and walk and sit straight. Having an erect stance always makes you look more confident, attractive, and masculine, so always have that poise in your posture which shall make you look awesome. Wear your confidence and attitude - Last but not the least is this most important pointer and that is - be comfortable and confident with whatever you wear and however you look. Being confident makes you win half your battle, always. So, have that debonair attitude and head to the floor, you will always be the head turner of the show. So what are you waiting for? Start your preparations, as being handsome does not require any occasion!        
Male infertility : An overview of the causesWhy men shy away from infertility tests? However, it is ideal for both the man and woman of a relationship to get infertility tests done. This would not only avoid unnecessary tests and expenditure later and could also result in prompt medical treatment of the problem. Following an appointment with a urologist/andrologist, the patient is instructed to provide a semen sample for analysis of the quantity and quality of the sperms in the semen. An additional semen test might be recommended for confirmation of the initial results. The semen analysis is an effective method of knowing what is going wrong in the reproductive system : No-sperm count (azoospermia) - Absence of production of sperms or the non-appearance of sperms in the semen. Sperm Morphology Issues - Issues related to the structure and form of the sperm. Low-Semen Production (oligospermia) - Production of low amount of sperms. Sperm Motility Problems - Abnormal movement of sperms resulting in incapacity to fertilize egg. Did you know that use of laptops placed on your thighs can result in increase of scrotal temperature? This could lead to abnormality with sperm production. Thus, using laptops is best when they are located on table or desks, away from constant contact with your genital region. There could also be a primary medical condition, the symptom of which could be manifested reproductively. The physician will suggest blood and urine tests, among others, for the same. There can be 10 major causes of male infertility : Semen : Semen refers to the ejaculated fluid containing sperms during sexual intercourse. There could be low or no count of sperm. It is also possible that the mobility of sperm is restricted. Sterilization : The cutting and sealing off the vas deferens (the tubes which carry the sperms from testicles to the semen) ensuring that your semen does not contain sperms is known as vasectomy. Though this process can be reversed, they are mostly not fruitful. Lack of sperms : Even though the testicles are producing quality sperms, it is possible that they do not reach the semen. The lack of sperms in the semen is medically known as obstructive azoospermia. Such a condition could be caused due to the blocking in one of the constitutive tubes of the reproductive system. This could be further resulting from an infection or a previous surgery. Ejaculation issues : Some men might find it challenging to ejaculate normally due to retrograde (ejaculation of semen into bladder) or premature (ejaculation in very short period of sexual activity) ejaculation. Medicine and drugs : Certain medications have been found to catalyze the onset of infertility. These include sulfasalazine, chemotherapy, anabolic steroids, and herbal remedies (for instance, the consumption of root derivates of Tripterygium wilfordii). The quality of semen can also be negatively affected by illegal drugs like cocaine and marijuana. Testicles : The function of production and storage of the semen lies with the testicles. In case of injury to them, the quality of the semen could be negatively affected. Causes of injury to testicles include a congenital defect, testicular infection, physical trauma, testicular surgery or cancer and undescended testicles (case where one or both of the testicles do not descend into the scrotum). Hypogonadism : This refers to the presence of a very low level of testosterone (male sexual hormone) which plays a major role in production of sperms. This could be due to tumors, Klinefelter's syndrome, or consumption of illegal drugs. Sexually transmitted diseases (STDs) : A series of sexually transmitted illnesses can result in male infertility, for example, chlamydia. Alcohol and weight : Consumption of over 3 to 4 units of alcohol per day can result in infertility in men. Both men and women are affected adversely due to obesity. Occupational factors and stress : Contact with certain types of pesticides, solvents, and metals can result in deterioration of sperm quality. Stress has also been associated with the loss of sexual drive resulting in lesser instances of sexual intercourse. Moreover, in case of severe stress, sperm production can be unfavorably affected.
Infertility at workplaceSince infertility among the younger age is increasing, it is important that a couple decides an early suitable date to attempt conception. Time and again it has been found that infrequency of intercourse is the cause of delayed pregnancy. It is advisable that the woman has a thorough examination by the gynecologists to identify the ovulation dates and for the man to have a thorough spermatic fluid check.  If both are normal then they could wait for a suitable date later. Should there be a problem the quicker it is attended to better. Also, early in the marriage they should start a fund which could be utilized for matters related to conception. For the male, the main treatment covers his personal sex life and a detailed examination of his spermatic fluid. It is the female who has to undergo many detailed tests and possibly surgeries which are expensive. It is often seen that not only the procedures for both take a toll on their personal and intimate relationship but also severely affect their finances which may come to a point that it does not allow them to complete the treatment as for e.g. the woman undergoing IVF may costs several lakhs of rupees. The treatment of infertility has improved greatly, but interferes severely with the work schedule. Working couples particularly women may have a hard time keeping to their schedules. Depending on their infertility diagnosis, many workplace challenges exist including the need to take time off to undergo tests and other appointments. It is difficult to balance the medical and surgical procedures with daily life and work. This is a difficult issue for many people as they fear their employer may discriminate against them for taking time off from work. Sadly in India there are very few employers who include medical benefits and cost of treatment for infertility. Suggestions have been given on stress dealing with infertility treatment and work. Here are few pitfalls to avoid: Do Your Homework: Review your organization's HR policies so you understand the amount of leave you have and other policies that pertain to your situation. You may be able to arrange for flex time or work from home on the days of your appointments, so that you do not actually miss any work. Be Honest:  Go to supervisor and let her or him know that you will be using your leave time and will give as much notice as possible. Honesty is the best policy. Remember people are inherently curious about the disease of infertility. If you feel the questions are invasive and make you feel uncomfortable, remember you do not have to answer the questions. You can respond nicely and let them know that you appreciate their concern but you are not ready to answer any questions. Your co-workers are asking question because it is human nature to be curious. In conclusion, not everyone needs to know what is happening with your reproductive health. At work place should medical help be available do take advantage of it.  This treatment has nothing to do with your performance at work. Go to work feeling confident that you will be able to perform your job and handle your workload during this time.
Marrying late in lifeConventionally, the marriage age is determined according to the linear formula of happiness that we have constructed and believe to be true. The formula being: getting married by 24 --> having children by 27 --> working (optional) --> becoming a grandparent (that too, real soon!). However, time and again, men and women wandering in their 40s-50s have woken up from the deep disturbed slumber to realize that maybe- just maybe, they had walked into things too fast. They had been unable to know who they are and to become a self-conscious human being before being ready to fuse their lives with another. The prime point of being single and marrying later in life is not to go on some form of egoistic joy-trip but to be able to know oneself and become ready to be the right person for the other. By marrying late, you give yourself time to experience freely what you like and dislike. You get to explore the world at your own terms- travel whenever you want and involve yourself in festivals and activities that manifest who you are. Marrying early doesn't allow for time to explore one's being, as marriage generally immediately follows the time you finish your studies or begin working. One of the most important aspects of adulthood today is travelling. However, every individual has unique wants of travelling and being a single adult will allow you to experience the world fully. You will also get in touch with yourself, exploring how you would like to live. The decision will arise from a ground of experiences which would clearly tell you what repels and what appeals to you. Such experiences are rarely findable once you begin living with another, as you would have to schedule your days and basically, your routine around the other's life as well. Financially, you have reached a point where you know how to take care and manage finances, allowing you to plan your wedding pragmatically. Marrying at a later point in your life allows you to be clear about when you would like to be a parent. Your experiences also ready you to be a considerate and understanding parent who can guide a child. As you grow older, you tend to become more tolerant and the propensity towards differences turning into unnecessary fights is lowered. As our ways of looking at the world change, every person as an individual has the need to learn to see the world as a home. This feeling of being at home is created only through series of experiences one has to go through as a responsible adult. In the face of inexperience, two individuals coming together often find themselves incapable of being happy with one another. Marrying later allows you to have grown into a wiser person yourself before sharing your life with another.
Boost your mood after a long day at workUp before the sun rise, rush to get ready, say hurried goodbyes to the family and crawl like a tortoise through traffic to get to work. Go through a long day of meetings, calls, deadlines, reviews, and then crawl back again through traffic at a snail's pace. Does this sound like a day out of your life? Then surely, weekends go by faster for you than you can say lickety-split, leaving with no time for yourself, your family or your hobbies. Social life is definitely a far cry from possible. This rigorous schedule eventually catches up with the mind and body and lethargy sets in, discouraging any sort of activity that breaks the monotony of day-to-day life. Is there no escape from this? Yes, there is. At the end of the day, when your mind is tired, you do not feel like taking anything more than you already have on your plate. Only the warmth of your bed allures you. However, if you were feeling fresh and enthusiastic, surely, you'd be ready to do a lot more - move mountains or at least drive to meet friends, anyway.

Faking illnesses - An illness in itself?In 2008, a 28 years old woman in the US shared some shocking news with her friends. She had been detected with cancer. She posted updates on social networking sites and wrote blogs on her illness. Sympathy poured in from all corners. Some even sent in monetary help to cover her expenses. The saddest part of the incident though was not her cancer; it was the fact that she had faked it! Police investigations revealed her little trick when no evidences or records were found at the hospitals! Apparently, this isn't a unique case;  faking illnesses or malingering is a very common occurrence. All of us have done it at some point in our lives. While we may have done it to escape a school punishment or to take undue advantage of the office 'sick leaves' for personal purposes, it is usually done on a harmless level. But faking illness can be a chronic disorder too and  medical professionals even have a name for it-; Munchausen's Syndrome. People suffering from this syndrome fake illnesses that they don't actually have, to gain sympathy or simply to be the center of attention. Usually gaining sympathy is the main reason why people fake illnesses. It gives them a chance to be in the spotlight. Everyone calls and visits, expresses concern and fusses over them. Lots of love is showered upon them. Another common reason for faking illnesses, is money and at times, the monetary benefits are higher than the emotional ones. No one hesitates to fulfill the last wish of a dying person, however expensive it may be. Often there are mixed motivations and the person faking an illness has many reasons to keep up the pretense of being sick, for as long as possible. Some people really do have a disease — a mental illness known as a factitious disorder. People with this disorder pretend to have an illness, which is usually a terminal one and often go to great lengths to maintain their hoax. Munchausen syndrome by proxy, is another form of faking illness. People with this disorder, fake illnesses of people under their care; and they usually do this, for monetary benefits. Children are the most common victims in this disease. When you tell someone that your child has cancer, you will receive a great amount of sympathy and all the money you want, no questions asked! People with these disorders are extremely cunning. They go to great extents to maintain their lies. They will build grand stories, complain of fake pains and aches, get admitted to hospitals and undergo a battery of tests, numerous times. Interestingly, they never allow and frequently discourage medical professionals, from talking to any of their family members. Since they know they are faking the illness, they will refuse to undergo treatment, for obvious reasons. . If you think a loved one may be exaggerating or faking their health issues, attempt a gentle conversation, voicing your concerns. Avoid anger, judgment or confrontation, while offering support and care and if possible, help them in finding a treatment. Treatment includes empathy, helping in identifying feelings and issues that led to the development of the disorder and finding  alternative healthy ways to deal with those feelings and issues.
Top 10 tips for weight maintenanceTIP 1: Stay Calm and PlanDon't worry about your weight excessively. This will only result in stress which can be counter-productive to your pursuit. Remember that you have reached the goal you had to and you are strong enough to sustain it. Take one day at a time. Do not think about how you are going to keep it forever. Just focus on the next day. TIP 2: Health JournalKeep a journal where you note down your eating and exercising patterns. Write down what you eat, plan your meals, drink adequate water, and form an exercise regime. Did you know that you can include an activity within your life as a habit by performing it for 21 days? Do these things not because you have to but because they are good for your health. Slowly, they will become a part of who you are. TIP 3: Being Healthy Is A Lifetime DealOne of the greatest mistakes that people do is to think that once they have lost weight, they can return to their early eating habits. Remember that your health is with you for life. Shift your perspective from 'I have to become thin' to 'I have to be healthy.' Once you do this, you will find it easier to stay healthy for the well-being of your body. TIP 4: Be RealisticWhen you are planning your lifestyle, don't take up unrealistic goals. This is one of the reasons why weight-trainers say that the best way to reduce and sustain right weight is to make it 'your life.' Eat right, sleep well, and drink lots of water. These three, if done properly, can help you to have the right body weight. If you have any rules like 'don't eat cake or pastries ever,' 'quit drinking,' then rethink about them. Are you going to be able to never eat sweets? The primary goal is to make a balance, choose the middle path. TIP 5: Get An Idea Of Your Weight-PatternMany people stop weighing their body once they have reached the ideal weight. They think that the scales are only for the fat ones. A person with such a perspective is only looking for slim bodies and not healthy ones. Remember that your weight is not a judgment of your appearance, but a barometer of your health. So do not stop doing the weekly weight checks. Keep a report of your weight every week and check out the causes for any abnormal changes. TIP 6: Accept Your Limitations And Learn From ThemEveryone has their ups and downs. Don't get discouraged and be angry at yourself if you binged on a donut on a cloudy day. Everyone makes mistakes. It is not the end of your weight maintenance. It is simply a blip. Learn from it. Know what the causes are for it and work on making sure you react to the cause differently next time. TIP 7: Thirst And HungerYour body could confuse your thirst for hunger. So, if you are feeling hungry really soon after your previous meal, then start by drinking a glass of water and check if you feel better. If you do not, then it is time for a light healthy snack. TIP 8: Inspire YourselfWeight maintenance is primarily a psychological task. Till the time you were reaching the ideal weight, you learn everything you had to about being healthy. Now, you have to make sure you don't let obstructions stop you from sustaining this healthy lifestyle. So, join other people who are only in the process of maintaining their weight. Become part of the running blub or catch up with a health conscious friend regularly. TIP 9: Mind Over MatterBalance your eating patterns. If you think that you will be going out for lunch, then have a healthy breakfast and cut down on the dinner. You might be craving for a dessert, so you can have salad for the main course and treat your sweet tooth. Talk to yourself about what you are going to eat. Ask yourself if you really want to eat it because you are hungry or are there any other reasons for it. How would you feel about it after you are done eating? TIP 10: Celebrate Your AchievementsLastly, be proud of your weight maintenance program. Celebrate the fact that you worked hard towards making sure you have a healthy body and invite people who were part of your pursuit. Embrace your body and toast to the next year of a healthy lifestyle.
How to communicate with a patient who has a strokeThe first and the most important thing to communicate with the patient, is to give undivided attention. Give attention to his activities, gestures, his facial expressions through which he may try to communicate so his feelings could be understood. Eye contact is also important but the patient having stroke may look at you square in the eyes but he may not respond to your conversation. While communicating with the patient you should always stand in front and tune out all the other sights and sounds in the room. Maintain full silence around the patient in the room, turn down the volume of the television, radio and ask other people in the room to be silent. You may communicate with the patient by making contact by touching the hand, chin, cheek or areas which are not affected by stroke. As the side which is affected by stroke, does not have any sensations. You may communicate with the patient through his family member by telling the family member to communicate with patient by saying, "Look at my face"; through this we can gain the patient's concentration. You should always speak clearly with the patient in a normal soft volume. Express your ideas in simple terms, form simple sentences, do not use complex words. You may repeat the sentences or an important term again. For example to ask if the patient wants tea, repeat the word 'tea'. More complex thoughts can also be similarly conveyed and repeated. You may also use hand gestures with clarification like doing Hello by waving your hand or through your hand action, you may ask questions like, How are you? Are you ok? What do you want? Through this both caregiver and stroke patient can benefit. You may ask your patient to point out whatever he wants or if he needs anything. And gradually he will develop the habit of pointing the daily items like television, newspaper, remote, eyeglasses radio, drapes an uncomfortable foot, the patient can indicate any pain or headache. Through this communication we can make the patient learn, use mechanical lifts to get in and out of the bed, and with the help of the attendant by demonstrating the patient how to use it. Sometimes when the communication does not work, take a break, give it time and try again, do not get frustrated and reassure the patient that yes, he or she can do it. Good communication with the patient is very important as they cannot speak their basic wants and needs clearly. The patients suffered a stroke also have slurred speech. There is a deviation of the angle of mouth. They are mostly bed ridden and could not carry out the routine activities.
Stress-free sex: Know your safe period!Having sex is a pleasurable thing; and the nicest way to enjoy it, is to give in without being bogged down by the fears of getting pregnant. Not every act of sexual intercourse will result in pregnancy. There are days when your chances of conception are very high, just like there are days when the chances of getting pregnant are almost nil. Identifying these days will help you enjoy a better and a more stressfree sex life! A woman's menstrual cycle starts from the first day of  bleeding and ends about 28 days after that, on an average. Ovulation occurs on the 14 day of the menstrual cycle. The 14th day is the ideal day, theoretically. Since every woman's menstrual cycle differs, the day of the ovulation also differs. Hence doctors calculate the fertile period from the 12th to the 18th day of the menstrual cycle. This is the period when the chances of ovulating and hence getting pregnant, are optimal. The 1st to the 7th day and the 19th day to the start of the next cycle, are the days when the ovulation chances are very low. This means if you make love during these days, there are very little chances of you getting pregnant. This is the case with women who have regular period cycles. In case your cycles are not regular, then you would need to do a bit of math to calculate your safe period. For example, if your shortest cycle is of 26 days and the longest cycle has been of 31 days, then: 26-18= 8 and 31-10=21, which means the 8th to the 21st day of your cycle, are the most fertile days. The 1st to the 7th day and then the 21st day to the start of your next cycle, are the days that are safe for you to enjoy sex, without fear of getting pregnant. Opting to have sex during the 'safe period', isn't always fool-proof though. A lot of women have irregular cycles and the cycle length can vary from woman to woman; which is why the so-called 'safe period', is in truth, not 100% safe. It is always better to use condoms or other contraceptive methods like the oral pill to prevent unwanted pregnancies.
