A career for someone like me? :)?

I am looking for a career that I won't end up regretting, because if I don't like it, no amount of money is going to help me! However, I would prefer a career that not only is interesting to me but also has some decent pay! I don't need to go overboard with the $100,000 salary but I would like at least $50,000-$80,000. I do not want to be a doctor, or a dentist, or an EMT. I want to help people, but I have a weak stomach so I cannot tolerate seeing the inside of someones body, or some dead, rotten corpse. I cannot testify in court, nor can I persuade others. I don't want to look into a microscope or at a computer all day either! I am a small person, so I can't do anything that involves heavy weight. I do not mind doing math, because I love a challenge! I also like learning new things. I want a job that is mentally challenging, exciting, where I can help people, where I can learn new things while on the job, and that pays a reasonable salary!
