Time of life (with apologies to Zeno)

I have reached that time when I measure my life not by the years but by the months. Thus, I lengthen my life. I say to myself I may have only 6 years remaining, but 72 months is another lifetime. Soon, I will do the same with days and hours, then minutes and seconds. Each new measure will push life’s horizon back to a safe distance. The question is, of course, how long can I get away with this sort of time-chopping. Theoretically, forever.
