I'd be working in banking, probably ending up a commercial lender since there would be a vacuum for the VP and a few other positions in a few years as they were all in their early 60's. Would've been a guaranteed "you literally can only get these jobs with experience" type of deal for me. No bank hires commercial lenders without experience. They won't even hire college grads who studied it. Way too many obscure things you can only learn in the industry. So you still have to work your way up!
With my current knowledge? Probably some sort of woodworking. It is very satisfying. But I actually don't know how or if it is profitable in any way.
