Baltimore Checkerspot butterfly on Black-eyed Susan

Birthday time again.  Carol, the boss, came up and whispered low enough that the other people couldn't hear, "Happy 63rd!"  Guess she's still too young to realize that at this age:
(1) you really don't care how old you are.  Just as long as you are feeling good, can do what you want, and people think you are younger than you actually are, you are good to go.
and
(2) you are in a countdown to 65 when you are eligible for Medicare.
