Just doing a fast count of things I can say that I have been in about 20+ survival situations. Everything from an engine failure in an aircraft that I was flying alone and landed in a tree 30 miles in the middle of swamp, onset of hypothermia while camping with no way out until picked up in 7 days, broken leg while in a forested combat situation to a poisonous snake bite 15 miles into the bush. All had an element of death if I did not react decisively. In some, the decision was not something that had to happen in the exact moment the situation started but was a calculated decision over days.
