In all seriousness though, I'm one of those hardcore science nerds and one of my many interests is geology so I've been collecting mineral specimens all my life. For a few years I went through a phase where I collected radioactive minerals and amassed quite a collection. I spent weekends digging through the tailings of the old uranium mines in Bancroft, Ont (interesting enough the same locale where much of the uranium used in the Manhattan Project was mined). I kind of regret selling some pieces seeing they were pretty much rare and irreplaceable. I even had a sample of ore from the former USSR from the same locale that they mined the uranium for their first atomic bomb tests as well. I still have about 10 kilos of pitchblende sitting in a box buried somewhere in the basement.
If I was banging all of them, I'd be a manwhore. At the moment, I'm just an opportunist.
