I wore a tank top today. While that may not seem to be noteworthy, if I add that I am 50 years old, than the fact that I wore a tank top, in public, becomes significant. Most women start to cover their upper arms when they turn 30. I certainly did, feeling that no matter how young the rest of me looked, flabby underarms would be a giveaway that I was not only out of shape, but old.
