You know all the warning signs of a heart attack. Nobody ever tells you to slow down. Your eyebrows look like shrubbery and your wife's have disappeared. You have a party and the neighbors don't even realize it. You have to get a permit to light the candles on your birthday cake.
Comfort takes the place of fashion.
You can't sit still without falling asleep. You start believing that you really did walk five miles to school barefoot and in the snow.
