robert,
you certainly to look fearless to me
how does it feel to not exist?
you may want to come close(but just close) to an answer to that question if get rid of your senses bit after bit and everything else until just the brain alone keeps on living (sure it will (if available) require some artificial instruments to support it) - and sure that might hurt (maybe the come up with a solution for that as well) - no brain - no you.
so you better don't want to know that.
