I've got 20 years left, on average. I'll purge everything not necessary for daily life before the end. Stuff like test equipment, parts, and other things that I had previously kept as mementos or spares will be given away, or pitched.

Don't leave a ton of shit for your heirs, they'll have to hire someone to throw it out. It's not valuable, really.

Other than that.. just try to help those who need it, and do my best to make the world a better place, one repair at a time.
