One cup of coffee, an egg or two, some cereal and toast, no red meat, no potatoes.
Walk to your office if it is less than three miles; if over three miles ride the extra distance, but walk three miles anyway.
Walk alone. This is most important; it relaxes your brain. Walking with company makes it a physical exertion and a mental pull as well, for a man will talk when he has company.
Eat a light lunch; be sure to eat an apple; with it drink two or three glasses of water, cool but not cold.
Let your hearty meal be supper, eat slowly and don't talk business. After supper play with the kids or joke with your wife; get a smile on your face.
Just before you retire read a chapter from a worth-while book. The last thoughts which you take in at night are the ones which stick.
Leave your business in your business clothes, and get in a good night's sleep.
Keep a sharp look-out for tendencies to change your habits and morals.
At 50 you are walking on thin ice; look out, danger is near.
After you are 55 your habits are pretty well established. If you have lived rightly till then you're safe thereafter and likely on your way to a good ripe old age if you take reasonable care of yourself.
