Stocking up on some Christmas cheer last week, I was asked to show I.D. for my purchases. Never one to begrudge being carded, I pulled out my driver’s license and showed it to the young assistant.

She gave it a quick look, did some math, and said, “Wow, you look good for 42.”

Even as my ego puffed up faster than an inflatable Santa lawn ornament, a quip sprung to my lips.

“That’s because I don’t have kids,” I almost said.

It’s true I only have a few errant gray hairs and my worry lines are small and faint, and it’s also true that friends my age who do have kids generally have a lot more gray than me under their highlights.

So, I wonder, is it genes that have kept the gray away, or was the young woman just a bad judge of age, or could looking younger be a perk of not having kids? What do you think?
