Often say to my wife, if I had to do it all over again I would be an auto mechanic (been IT Project Manager for about 20 years now). Love the art of solving/managing problems/solutions and am good at it but fed up with the stress. I'm 50 myself and recently signed up for a welding class just for fun. Also bought a vintage VW beetle to restore. Though I find I curse more working on the beetle than I ever do on IT projects.
