I feel sleepy and grumpy, but don't tell Snow White.
The thing that puzzles me is, how am I supposed to feel "for my age"? What is my age supposed to feel like? Is there a government database somewhere that defines it, or should I visit my friendly local physician to determine how I "should" feel?
The only usable scale I have access to right now is looking at my fellow human beings, and that's all over the place- there are 56-year-olds who run a triathlon every weekend, just as a break from their weekday job of mining coal with their bare hands.
Then there are the 56-year-olds who have morphed into being part of their recliners and are covered in a thick layer of Cheet-O's dust and sticky soda residue.
I answered that I feel "younger" because I have encountered more of the latter group than the former. I'm not in the hospital, not taking drugs, not experiencing aches or pains of any kind, so I consider myself both lucky and "young".
