It seems you've managed to get yourself bitten by a snake. Congratulations! That's quite the accomplishment.
Tip 1: Stay calm. Panic only if the snake was venomous. Otherwise, try not to think about the 27 different types of parasites it might have left in your system.
Tip 2: Don't try to suck out the venom. That's just not a thing you can do.
Now that we've got that out of the way, here are some more general survival tips for the snake-bitten:
DO NOT TRY TO REMOVE THE SNAKE BY HAND! You'll probably end up hurting yourself more. Or, you know, being dragged back into the depths of the jungle.
Instead, try to slowly back away while keeping a safe distance. If you're in the city, just get to a hospital. If you're in the jungle, try to find a nice, snake-free hotel.
Tip 3: Learn how to identify venomous snakes. It's not as hard as it sounds. Just remember: if it's got a funny pattern on its belly, it's probably not a cobra.
Tip 4: Practice your "not-moving" face. You know, for when you see a snake and need to freeze in place.
What's next? A bear? A spider? A zombie apocalypse?
