Any field that requires a certification and cannot be done from a computer is worth looking into.

So... any trade?

Some trades are more physically demanding on the body. I was thinking more along the lines of any field that requires a gov't license like nurse/counselor/barber/pharmacist/CPA/lawyer/administrator/teacher/air traffic controller/operator of some heavy machinery.

Not really. In the US the apprenticeship programs are pretty guarded. You would be better off saving your money wisely.
