History of lyme disease, malaria, and God knows what else I've picked up in my travels. I feel I've taken this as far as my body will let me. I work at a very large hospital, physically speaking and I walk about seven miles every shift. Not to mention lifting, carrying, etc. I've got two years ICU experience (it's a second career, body was already kind of on a downward trend). Any suggestions for career paths? I do want to go back to school. Thanks J
