I'm 55 and have the "lift thingy" already. Mostly use it for my own stuff, (very) occasionally I will do a side job for someone else, I don't like "big" ones that keep the lift tied up more than a couple of nights after work.
I know of people 20 years older than me that admittedly run circles around me, but I'm already finding things that used to take me a couple of hours take me a day or more..... Some things always did take me longer than the same thing takes others I know..... Story of another thread, there.
But yeah I get tired of shoddy work too. I trust nobody else to work on my vehicle but me. When I have to have something done I'm right there watching the work done.
