I can't think of a single occasion where you would have less than a minute to live and no other major circumstance being present to kill you. If it was a gunshot or other lethal injury that I remained conscious through, I'd probably be in shock and so I'd be pretty calm and reflective on my life with peace of mind. If my life was being threatened with death by an executioner or fire/ water/ etc, and I knew I had no chance of survival, I'm sure I'd be quite a bit more apprehensive of the process of death in itself. I don't think that either of these are really getting at the heart of the question though, so maybe the time period allotted should be extended a bit to allow thinking about something other than the fact that you are being killed.
