Hey G.T.,
Health issues, ... yeah, I got 'em as well at 72. Lucky I can walk unaided around the grocery store after standing 5-6 hours at work. As far as work and skill set, I'll drop these here for you and any interested parties to view. Wondering what I'd be when I finally grew up, ... I've been doing this type of think since 1985.
I've worked for Robert 10+ years. I'm his Drivetrain specialist, engines, transmissions, rear axles. I also make any needed extinct small part, you need it, Caveman can make it. All the cars you'll see here usually get a fresh engine, trans, rear gear set-up. My DNA is all over them;

The above is not stock under the hood Carrillo pistons/rods, 5/16 stem Ferrea valves, ported and polished head, Extrude honed intake manifold, higher compression. 280 HP, OEM was under 200.
The Maserati in the above is before I did the complete engine, it's running there with 2 completely flat intake cam lobes. The vid below is after I went completely through it;
