     Good health is the most precious thing in the world.When you have got it, you never think about it.

When you haven't got it, you think about it all the time. Our biggest enemies are not terrible diseases. We

are our own biggest enemies because we sometimes destroy our own good health. Some of us eat too

much, drink too much and smoke too much. And though our reason tells us we should control ourselves,

we find it difficult. The fact is that most human beings need stimulation.(刺激) Who doesn't enjoy a drink

after a busy day? Only a smoker knows the pleasure of a cigarette with a cup of coffee.

     The danger is when these innocent pleasures run our lives and so destroy our health. When you find

yourself eating between meals or eating too much rich food, when you can only keep yourself going by

taking frequent drinks or by smoking one cigarette after another, then it's time to stop and think what you

might be doing to yourself. The funny thing is that when we don't control ourselves, simple pleasures are

no longer simple pleasures.

     All right, I know what you're thinking. You're probably saying: "It's all very well for him to talk, but I

can't help myself. I need that extra bit of food, that extra drink, that extra cigarette. Life has so many

pressures that I can't manage without them." But I'm saying you can help yourself. Not only that you must

help yourself. Because if you don't help yourself, no one else can. So be your own best friend.
