A lot of men are a little vague on exactly when middle age begins. It has nothing to do with your chronological age, and it doesn't matter if your hair has gone gray, white or AWOL. You have officially arrived at midlife when the most important aspect of any given activity is comfort. In midlife, excitement, adventure and even finances all take a back seat. What you're looking for is comfort. You're not interested in physical fitness, you want heating and air conditioning. You want padding -- on your furniture, on your paycheck and on your own butt. Even your love life is affected. Forget passion, what you want now is a "comfortable" relationship, where nobody yells at anybody, nothing changes and nine times out of 10 you fall asleep before your wife does. Your wild oats have turned to Wild Oat-Bran. As middle age progresses, you'll probably even become "comfortable" with yourself. Some call it giving up. I call it true success. When you can stand in front of a mirror or a banker and say proudly 'This is as good as I get,' hey, that has to be a comforting thought.
