Carpal tunnel isn't about being sedentary, is it? It's about repetitive movements (from people I know who suffer from it, vibrations also exacerbate their conditions, which is why I brought up power tools) - just like the common plumbing activities that I mentioned. This isn't about aches. If your body can't handle sitting at a computer, then you are out of your mind thinking that working a trade will somehow 'be better.' Buy a standing desk, ergonomic keyboard + mouse, and go for some walks.
