Let's see now. How will I know when I am a senior.
Hmmmmmmm.....
Some places give me a senior's discount at 55, some at 60 and some at 65.
My government pension will be sent to me when I am 65.
My company will arbitrarily retire me at 65. (I'm going to beat them to the punch
and retire at 60.)
So that means that parts of our society think 'senior' begins at 55.
How will I personally know?
Well, with a little bit of luck, I don't think I'll ever know.
It's all in how you play the game, isn't it?
