I've been a mechanic for 35 years.
I repair horticultural machinery for a living. Had ten years out when I repaired plant equipment, and went back to garden machinery on a self employed basis about 16 years ago. Still doing it now.
I dabble in computing, website building, and electronics, and even just yesterday had to rip the motherboard out of this PC to cure some major lockup problems. Robbed three capacitors from a old motherboard, and replaced the bulging ones on this one. Works as you can see, because I'm typing this post on it.
