OMG. You are really old! Don't ever do anything except stay in your bed and ruminate on your life gone by.
OK, OK, I might have misspoken. :)
My father died at his age 37. My mother died at my birth at her age 32. My maternal grandparents (bless them) adopted me at my age 7 at their respective ages of 72 and 70. I still have a hard time wrapping my head around that concept. They died respectively at my age 15 and 16. I was one of the 1st emancipated minors in my state's history.
I laboriously said all of that to say this:
I expected to leave this life many years ago, I have lived life as if there will never be a tomorrow. So far, so good. Still, if I go tomorrow....well done.
Therein is the essence. If you can go to sleep tonight secure and happy with yourself, Well Done!
And no, given physical limitations, there is no such thing as "too old".
