Often , drinking, smoking and eating badly won't begin to take its toll until after the age of 40. Health checks in the 20s and 30s will not save many lives. Wearing a condom for casual sex and driving carefully with a seatbelt and airbags will offer more protection against an early death. However, this doesn't mean that young men should think of themselves as invincible. For one thing, they don't all have the bodies of footballers, pop stars or ballet dancers.
Good health is about much more than just staying alive.
It is about staying active and enjoying life. Men who start good habits in their youth will be forever grateful to themselves later in life. They will begin to see the effects of smoking, over-drinking, lack of exercise and junk food in their contemporaries. If they have kept out of the sun and looked after their teeth, they will look even better. However robust and fit a man was as a youngster, time will catch up on him.
