I have had letters from people in Canada and from others in Florida who have suffered nervous breakdowns. In California some go to pieces. I have had many letters from people living there who have broken down. People also break down in Colorado and in New York; in fact, in every state in the Union. Climate does not seem to make any difference so far as this trouble is concerned, with the exception that in high altitudes I have observed nervous people are inclined to be more restless than elsewhere. Some years ago I went up Pike's Peak, to the Summit House. I went to bed and spent the night there, but I do not say I slept, for in reality I slept only about half an hour. I was not at all sick at the stomach, as so many are who climb up there; I had prevented this by eating a very light breakfast and chewing my food to a cream. But I was extremely nervous. I have found a great many other nervous people who do not feel quite right when in a high altitude. As a general rule, sea level is as good a place as a nervous individual can find to live. But people break down there, too. The diet, you see, is the big thing. And when I say "diet" I mean the way food is eaten and the amount eaten quite as much as I do the kind of food eaten. And once more let me say, systematic outdoor exercise also counts, and you can't keep fit if you exercise only one, two, or three days a week. Some people who take long walks in the country on Sunday think that will suffice. But it will not. You must have exercise every day and must have some play along with it. Gymnasium work is of very little value as compared to outdoor exercise. In the summertime, gardening is a splendid form of exercise. And so is the care of a small flock of chickens, which is possible for those living in the smaller towns. It is always better, when taking outdoor exercise, to have something definite to do. When walking it is a good plan, if you can, to have some definite place to go. And if you have an agreeable companion to keep up a rapid-fire talk, that will help also. All these things are mentally stimulating. Then, if possible, sleep the year round on a sleeping porch. If you don't possess a porch, then, have all the windows in your sleeping room wide open day and night. If for a time you have to take physic, it is best to take some hot mineral water half an hour before breakfast. But adhering to dieting and exercise, and eating enough apples, usually overcomes constipation. Now, there are some things about which a person must use his own good judgment. For instance, if you have any bad teeth you should at once go to a good dentist and have them attended to. Nobody with bad teeth can have good health. Again, if your tonsils have become mere pus sacs you will have to go to a good nose and throat specialist and have them removed before you can expect to have good health. This, however, applies to all people, whether nervous or not.
