today I learned: like dogs, it is beneficial to lick your wounds. a variety of compounds in human saliva actually do speed healing. also, there is a really simple, low-cost, effective and reversible gel for men to not ejaculate sperm. injected into the vas deferens, the gel destroys existing sperm and lasts 10 years (but can be reversed anytime). next, getting annoyed at someone when we listen to them eating or breathing is called misophonia, and it’s an actual neurological disorder. finally, the famous photo of albert einstein sticking out his tongue was taken at the end of his 72nd birthday celebration. a photographer tried to persuade him to smile for the camera for a last time, but having smiled for photographers many times that day, einstein stuck out his tongue instead. bonus: a homeless woman in calgary found a purse with $10,400 in it and turned it into the police. she is good people.
