This is surely a common youthful perspective, but I would rather die even somewhat spectacularly now than slowly and feebly at the end of my bodily tether, unable to so much as stand on my own.
However, I couldn't have said that a few years back, as I had been living in neutral, unable to remember something of note from whole months of time. If I were to die tomorrow, I would certainly regret the things I had not done, but I would not feel my opportunities had been wasted, and would not have died simply watching the clock.
