well, I don't go out looking for danger or health threatening situations, but I remember a few that would qualify (in retrospect) as such.
Admittedly there was always a choice with at least 2 options, but once the dice had fallen there was no way back or out - and it was clear that 'failure' would be (more or less) fatal.
Yet I cannot remember any rush of exitement in these situations, in fact it was more the opposite, calm but extraordinarily attentive - using all personal skills it was just right to proceed the choosen way.
This feeling to do the right thing the right time in the right location turned into a peaceful satisfaction (afterwards), while during the 'action' the mind was almost empty - none of my drunk-or-drug experiences (decades ago) came even close to the intensity of these hours.
It's difficult to put im words, though, but looking back I regret a lot of 'wasted' opportunities due to just hanging around in my youth
cheers, Tom
