There is a problem with time in its reality,

When genetic early death seems like a real possibility there is a rude wake up cry for a middle aged person.  I figure we only truly have 2,000 useful hours every ten years.  So now you understand why people get weird.  Sometimes the math kicks in real hard.  In my case I have a greater concern and do what I can to avoid an early death, heart attack.  I know my risk from having an angina and heart problems in my family.  So that changes life.
