If you think dentists have it bad with seeing tooth decay and having bad breath blasted into their faces every day, try speaking to a podiatrist. Some of us have a phobia about feet - especially feet with long toenails, fungal infections or other hygiene issues. Such things would rule you out of the running to become a podiatrist. Tending to diseased, misshapen or otherwise irregular feet is the bread and butter of their occupation, so they probably develop an immunity to it.
A podiatrist will do more than just look at your foot, of course. Their field of expertise expands to the ankle and the whole of the lower leg below the knee, and they know so much about the physiology of that region that they're even licensed to perform minor surgeries - another factor which explains why they're paid so handsomely for their work. To become a podiatrist, you need a specific degree from an accredited podiatric college. You may have to travel for that; there are only nine of them in the whole United States of America.
