I was trained as a prosthetist and worked as an assistant prosthetist for 4 years. The reason I left? I don't like working that closely with people (the patients) and also the owner of the shop, whom I was stuck with for 7 hours a day in a fairly small space, had a split personality in my opinion. He could be whistling a tune and walk up to the office and walk back into the shop 5 minutes later and scream at me about something. I do believe it affected my health some and would have been detrimental to it if I had stayed.
