  • My son. It’s tanks. He’s 12 and can go on for hours about them, rattling off their armor thickness (in mm), caliber of their guns, horsepower of their engines, declination and traverse speeds of their turrets, etc. I took him to a tank museum one time, and no shit a quarter mile from the museum he sees the tank out front and he goes: “That’s a Sherman M4A4!!” Ten minutes later we’re parked and walking up to the museum, I look at the tiny info placard, M4A4, think to myself: “What the fuck.”










  • Seek says it’s a brown widow spider. From WebMD:

    Brown widow spiders are venomous, but they’re considered much less dangerous than the black widow. Although brown widow venom is just as toxic, the brown widow spider injects a much smaller amount of it. Also, only the adult female brown widow spiders bite. Immature and male brown widow spiders don’t bite at all.

    It’s actually interesting, the evolutionary trait that gave us the edge is actually sweating. Only humans, primates, horses and hippos really have the ability to sweat sufficiently to cool themselves. Canines and felines can only sweat through their paws, not enough to cool themselves. They can pant, but not enough for duration running. Primitive humans literally ran down their prey until the prey would overheat.
