Help me choose a career path in medicine?

I'm not in the medical profession, but I'm basing my answer on friends I know who have worked in some capacity in each of these specialties. Pharmacists' jobs are very stressful, require being 100% accurate at a very quick pace, have to deal with more grumpy customers, and are probably the most exposed to germs due to their contact with people getting their meds. They also often work long hours. Vets have to deal with all kinds of animals, not just dogs and cats, and often get bitten, scratched, etc. In addition, they are always on call for animal emergencies. My personal advice would be to be an optometrist as long as you are really interested in it. The work is slower paced, the patients are generally calmer, and you'd basically have a straight 5 dy/wk 8 hr/dy job. While they do work very up close and personal with people and are exposed to germs, it is less likely that their patients are sick at the time of their appointments.
