Snake bites

see https://www.snakebitefoundation.org/blog/2018/9/6/how-to-survive-a-snakebite-in-the-wilderness from article:
 * RETREAT. GET AWAY FROM SNAKE. GET TO DOCTOR
 * Remove watches/rings/bracelets etc in case your limbs swell up real big real fast
 * with marker, circle around bite, note time and swelling. repeat circle/time/swelling every half hour.  helps ID what bit you.
 * No NSAIDs. Snake venom fucks with your vessels or something, NSAIDS interfere with blood clotting
 * Epipen (presumably or benadryl if that's all you have) for signs of anaphylaxis

prep

 * avoid kits, they don't work AND they make things worse
 * marker
 * timer
 * ability to get to doctor (eg cell phone)
 * epipen (presumably or benadryl if that's what ya got)
