Lord knows my brother and I will inherit a ton of stuff from our dad... Personally, I don't collect as much as I did back in my high school/college years, as I've found I hate dusting more than I enjoy collecting. Like you, I also collect Hot Wheels occasionally, comic books (though mostly just Invader Zim,) bicycles and bicycle parts, and anything I can find for free on Craiglist or FB Marketplace that I can repurpose for whatever. I also like to collect car magazines, LEGO, classic car parts, especially brightwork, and movies/TV shows on DVD and Blu-ray. Most of what I collect these days are items I know I'll have a near-immediate use for, whether it's practical or just for play. I don't like collecting stuff that just sits on a shelf gathering dust. I want to read, watch, play with, or just simply use whatever I collect.
