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.
The same thing is true with regard to your eyes. If you are suffering from eye strain because you need glasses, you cannot hope to get well of "nerves" until your eyes are properly fitted to glasses by some reliable eye specialist. These are things that each individual must discover and do for himself. He should consult a dentist, an oculist, an aurist, or other specialist according to his particular need.
