It’s time to rant again about ageism.

This time, however, it’s not about those offensive intersection crossing signs that feature stooped over, cane-holding old ladies or those offensive birthday cards like the one for 50 — yes, 50 — “remember that ill-advised sleeve tattoo you got during your misspent youth? Think how it looks to your doctor while you sit in his office complaining of incontinence” or those offensive ads targeting clueless, brain-fogged old people who cannot seem to manage the intricacies of a normal cellphone.

Nope, this is about how older people are sometimes complicit in the creation and maintenance of these stereotypes. (In fact, as I wrote in Counterclockwise several years ago, unlike just about every other group on the receiving end of an –ism, a disturbing majority of older people actually believe the damaging stereotypes about older people.)

This was a video clip that came across my morning updates yesterday, a CNN story about “beating loneliness after retirement.” The story is about these old guys who don’t know what to do with themselves after retirement. Fair enough. So they go bowling. Now I love bowling. Nothing against bowling. But here is how one of the guys described his decision to join in: “It was either this or sit on the couch all day and watch TV.”

Seriously? That’s the choice?

If you have the energy and strength to go bowling (and yay for that), then you have the energy and strength to be a mentor to a kid who needs an adult in his life. You have the energy and strength to volunteer at your local food bank. To hammer a few nails for Habitat for Humanity. To go play with dogs in animal shelters. To tutor adults who can’t read.

To be visible and useful and show that you are a caring, contributing part of the community in which you live. Otherwise, you actively contribute to the stereotype of older people as useless. In the way. Just taking up space. And resources.

End of rant. For now.

Oh, P.S. Can I just say/ shout/ proclaim on high:
