It's kind of weird. I've worked both physical jobs and desk jobs, and could never imagine actually wishing a computer/desk job on either of my kids (thankfully they're not at all interested so far, so I think they've dodged a bullet). Interestingly, I have a good friend that was a bed-side nurse since she was 16 all the way through 36, at which point, she switched to a nurse manager position basically being behind the computer all day. This woman has worked a 12 hour shift most of her life, standing or walking, and lifting during the vast majority of that shift, yet couldn't understand why her back, hips, wrists and knees were killing her after 8 hours of sitting at a computer (not to mention her weight gain).
