I would take that pill in a heartbeat. I for one am scared of the gathering darkness which will consume me when the reaper knocks upon my door, to make the most of the time I do have would go someway to addressing that concern.
My greatest fear is leaving this earth without having made a significant contribution, seriously, if I ever get terminal cancer I'm going to attempt to write the great Australian novel before I die so I leave something behind.
If I took this pill, it would allow me more time in which to make this contribution. Thus, I would be more at ease with my mortality.
