I think it's pretty pointless thrashing out scenarios while we are sat at home in our nice warm houses sat in our comfy chairs.
If anyone has been in a emergency situation you know that your decision making process will differ dramatically when we are cold, wet and very worried.
If you plan on some things going wrong, we all know for a fact that it's the things we haven't planned on that will really ruin our day.
Personally i like to take responsibility for myself.
If i get myself into a emergency situation then i want to be prepared enough that i can look after myself and not put my life in other peoples hands.
I'm not talking about carrying a 10kg of tent, sleeping bag, food, stove etc on a day walk here, I'm talking about taking my time to select a few things that would help me stay warm and dry enough to live and signal for help.
A whistle weighs hardly anything, yet i have seen how useful they are in signally and locating people in need of assistance.
My bivvy bag weighs just over 100g and is smaller than a apple.
My FAK kit has been used many many times, be it coming across injured hikers, the people I'm hiking with or for myself.
I've used several on those packets of recover ice you see in my pic, even if it's not a do or die situation it's amazing how such a small thing can help improve both your mental and physical well being when you've twisted a ankle of the like.
I've used duct tape, paracord, knife to make a splint and crutch out of fallen wood to help a mate get down to a road.
Took us hours and he was in a lot of pain, but the ibuprofen, cool wrap helped.
We all make our own risk assessments based upon our own life experiences and knowledge, for me personally I'm happy to carry a few hundred grams of kit that i hope i never use "just in case".
My mate that [censored] his ankle used to take nothing with him at all, he has now had experience in what can go wrong and how someone is not going to magic you off a mountain.
Funny thing is, a few days after his injury he asked me to order him whatever i felt he'd need "just in case" for next time.
Should say that some people don't wear seatbelts, have no car or home insurance, don't have any savings or financial fall back, smoke, are morbidly obese, drink excessively, take illegal drugs etc etc etc.
So even when we have knowledge that something is not good for us, some personality types just ignore risks and continue anyway
