I think people who are into crafts. They have all of these yarns, construction papers, various tools and stuff. All so that they can say that they have all of these projects in mind that they want to do. But they never do them so they get more crafting stuff and it just eats away storage until their place is practically consumed by it.
Cycling can get bad. Some dudes have a garage full of $20k of bikes.
I am on the low end of the bike hoarding spectrum. I have two very modestly priced bikes (one road, one fat) and a 20” box of parts and accessories. You could count the 4 water bottles in the cupboard, 4 bike shorts in the drawer, and 6 bike jerseys in the closet as well. 2 pairs of bike shoes, a hook of tires and tubes in the garage, oh god never mind I have it bad.
This week I actually got to use some old cranks I had saved from a bike I replaced.
Ok I'm not actually going to ride those cranks. I just needed to fit them on the bike to confirm the other cranks were bent and not the bike frame itself.
Now I'm going to buy new replacement cranks and keep the old ones AND the bent ones for some reason...
