I'm seeking some advice from some veteran lineman. I've been installing and burying drops for about 4 years. I'm interested in going back to college for utility line for a couple of years. My only big concern is that my body doesn't know what it's in for. Just how hard is the lineman occupation on the body. I'm in my early 20's and can already feel the effects of tugging a 28' ladder around all day. I just don't want to feel 60 when I'm 30. What kind of a toll does it take on the body. Also, about how long does it take before one can move up to a supervisory position generally? Thanks alot for the feedback to any who reply.
