This totally freaks me out.
Anyways, in case of being bitten by a snake, here is what you should do:
“You don’t make a cut, you grab a piece of cloth (rip off your shirt, or anything that you can tie as a knot) tie that thing above the bitten area to isolate blood from going up (say a snake bit your hand, tie your forearm, or your arm if it took too long to find something to tie with). After you do that, start sucking blood out of the bitten area and spitting it out. I never dealt with snakes, but with scorpions, you’ll tell the poison is out if the black stuff stopped coming out. When you suck your blood, it will be impure color (red+black). You should be fine when the blood coming out of you is back to normal red color.”
