Does auto body or mechanical work require you to be strong (I'm a girl)?

I met a few gals that can really paint over the years, good hand eye coordination, and color matching ability's, but it takes its toll on your body over the years, its very strenuous repetitive work believe it or not, and takes a lot of talent to do the nice custom work, however the pay is good if you get in with the right outfit, and most painters start there careers in the bodyshop and not the paint shop, so there smarter than they let on, they just dont want to do body work anymore as it will really beat you up after awhile, as far as the mechanical end. IDK one of my old girlfriends is a mechanic for the California Highway Patrol. but as California is broke I wonder if she still has a job , hope so she was pretty cool,
