Career ideas without a lot of computer use. Please help!?

I have a medical condition that I can't be on the computer for more than 30 minutes at a time so I need to find a career in something that doesn't require much computer use or prolonged computer use. I don't like needles or blood and I would prefer to be outside if possible but working indoors would be OK. What type of jobs could I do? I have an associates degree but can go back to school for a bachelors if the career is suitable for me. I want a career, not just another job. Thanks for any suggestions.
