I sweat excessively in general and moreso while gaming.
So i believe i may have hyperhidrosis. I sweat a LOT more than other people do, even when I'm cold and/or not even any under pressure. It only gets much much worse once i do become too hot or under pressure. This makes for some pretty awkward interviews as i've got some job interviews and college interviews to do. The thing on my mind isn't "Will i get this place?" or How to deal with the next question. It's "I hope they don't offer a handshake after this because I'm sweating so much my trousers are getting damp from wiping my hands down".
As an avid gamer too, my keyboard and mouse get really slippery and disgusting while gaming. So much so that every 2 minutes or so i have to spend a couple of seconds waving my hands about in the air to give it a break. I've been considering getting a huge fan for my desk, but that won't solve the underlying problem...
