Badges. I used to collect badges too, when I was a kid, and still have some super-rare ones in big a hexagonal tin from the 1960s.

Now, it's graphic novels, mainly, and Doctor Who stuff - but not a completist, just stuff that I like. I also have a massive collection of corks (because I use them in my art) and had to work quite hard draining beer and wine bottles to amas so many...

Thanks, Rodrigo, for another entertaining and thoughtful read.
