I don't know. You are trading strange things here: Even if you like doing brickwork, is it worth the toll on your body? I've met a lot of construction workers: I've met fewer that are nearing retirement age that are still working - and generally, when they do work, they use the machines while folks who haven't hurt their back, shoulders, and other bits do the physical work. Not everyone needs mastery of something physical and not everyone needs to get "pride" or other positive feelings from work so long as their work isn't horrible and the hours aren't overly long. And I bet there are plenty of folks that would rather babysit this machine than babysit the machine at the fast food place.
