Nail clippers is a good one! And I often say the thought of sorting socks instantly puts me in a state of dread, whenever people comment on my wearing odd ones.

Explaining my stuff is probably less interesting than finding out what has you interested in the batteries, what’s going on there?

If you’d settle for some rando thoughts instead of explanation: My parents had a junk drawer for all the dead ones. I’m not so careful, mine are strewn about bags and drawers. I like to have distance between them, not sure why, I doubt it makes it less likely for accidental mishaps. I keep thinking I should take them for recycling when I see one, but then I should find all the others too, but I don’t keep track of what is where. I work in electronics and embedded systems, batteries can make my job harder, I avoid using them when I can. But I also did a unit on battery management systems and cell design in university, pretty cool things. I remember opening up some childhood devices, with those old alkalines that weren’t designed well for undervoltage conditions maybe, or perhaps the battery cells themselves weren’t insulated well enough? The casing was eventually partially eaten by the internal reaction that is always going on in there. The leak was kind of unnerving, it looked like a lichen but for some metal contraption. Parasitic things that grow off other things freak me out in biology, this reaction was pretty simple chemistry in comparison to the horrors of biological things, why is my stupid primate brain unnerved by it?
