From a Washington Post column by Theodore R. Johnson headlined “I went to a day spa—and came to terms with middle age”:

A recent birthday brought a realization long apparent but actively ignored: I am middle-aged. The younger element of Gen X, in which I claim proud membership, still believes the 1980s — when we were in grade school — were just 20 years ago. Somehow, we can think this while also laughing with friends that there’s no way our 30th high school reunion is this year. If it’s true that you are as young as you feel, Gen X will always feel like we just turned 28.
