had a u/g first aid course
painkillers arent relly any use as even if you can swallow them you will be too cold to ingest them - digestion shuts down very early
bandages - improvise - hats gloves etc, fix with tape
slings - improvise, use tape
recomended minimum duct tape and bivvy bag, bothy tent much better
space blankets are mostly radiation barriers and very weak and end up as lots of glittery confetti
most heat loss will be convection and conduction - sit on a bag in a bivvy sac pulled down over your head
luxury would be a candle inside the sac - make a hole by your face
cro will be at least 2-3 hours getting to you
major trouble = dead, cpr dont bother unless cold water caused
minor trouble = go home
be self reliant
