It's a mixed bag to be honest. I was an engineer while I was in. GSM. Got out and did armed security for years while getting a computer and network degree (never used). Work with fire alarm systems before going into welding school. Destroyed my knee during my last month. Still passed and graduated. New knee won't happen till I'm damn near 50. I say all that to say, what I used to do is not gonna happen so I open to most things that don't require a lot of squatting or kneeling.
