I'd probably either be a teacher and be dirt poor, or work for an insurance company and be burned out on policy analysis.
I wouldn't have a garage full of scale models waiting to be built.
I wouldn't have a book case full of air combat books and finished models.
I wouldn't have boxes of flight sim manuals.
Before I got heavily into flight sims, I played a lot of sports. I'm not sure if computers settled me down into a sedentary lifestyle or if it was simply a case of getting older. I do know that I started doing more flight simming and less volleyball when I got my first computer - a 486DX66 with 8 Mb of RAM and a copy of "Chuck Yeager's Air Combat".
