Good for you. I have 16 years troubleshooting electronics/ computer systems to the component level as a field engineer.
I have zero interest in building engines, never have never will. Years ago I did a lot of my own work, can’t anymore. It is what it is. Sucks getting old.
Thankfully, there are tons of people just like me that provide bucks to guys who do enjoy building engines.
Best racer I know, current world champion, does nothing but add fuel and check air pressure on his car, everything else he farms out. Everything.
So what, doesn’t make him any less of an enthusiast.
You seem to assume a lot about people, it isn’t a good look.
