I remember as a kid being told to suck the venom out of a snake bite. The “best case” scenario was getting bitten on your hand or wrist where you could then instantly get as much venom out as you could. If the snake got you in a location where you couldn’t reach yourself, that’s when your hiking buddy would help you out. This of course lead to many jokes on the theme of where the bite happened and the identity of the 2nd person. Somehow the question never came up of what happens when you are by yourself.
