I don’t run. I walk with my eyes closed, holding onto the bar that measures my heart rate. I up the incline a little. Up the speed. Little by little.

I like walking with my eyes closed, but I can’t do that out in the street, where I would probably fall and break a hip. But it works here, in the exercise room at the Jewish Community Center, where it’s never crowded and the mirrors never reflect any hot young and toned females reminding me that’s it’s been a half-century since I was one of those.

I am meditating on my new gravatar, and I know that if I were a half-century younger, I would have my own mythic Avatar. She would probably look at lot like Xena.

I would be a player. Or, more accurately, a gamer. I actually don’t know much at all about gaming, but I “know” some interesting gamers because I follow them on Twitter — because my son follows them on Twitter.

There’s a whole subculture out there of gamers — of bright, creative younger people who Tweet and FB and blog and tumblr and instagram and flickr and all of those oddly spelled connective mechanisms that people my age usually have to look up on Wikipedia.

I’ve become a real fan of Felicia Day, a young woman of so many talents and creative projects that she takes my breath away. There’s no point in trying to describe her here, since her website has all the relevant information. You really should check out her funky youtube video of her song “Don’t You Want to Date My Avatar.” I’ve even gotten sucked into watching her , The Guild. It’s like I live on another planet from these creatives.

So, I’m on the treadmill, meditating, sort of, on being who I am. Not a gamer. Not even a player. Just a little old lady whose heart rate is up to 135 and I do, indeed, need to take a breath.

I open my eyes and look straight into the mirror into the mirrored eyes of a really good looking gray haired guy, who is working out at one of the machines in front of my treadmill. He smiles. He can’t be smiling at me, I think, but I smile back anyway.

Later, as I get up from the ab-crunching machine, he’s standing nearby, cooling off. He obviously takes this exercise thing a lot more seriously than I do. At least I get that impression from his trim physique and the gym shorts and fingerless gloves he is wearing. “This is a good time to come here,” he says to me. (It’s just a little after noon on a Sunday, and the place is almost empty.)

“Yes,” I say, smiling back. “Except it’s such a nice day out there. It’s a good day to be outside.” (Duh! What kind of a response is that??) For a minute we talk about the weather. I move on to the recumbent bike. He moves onto the the free weights.

Now I’m pedaling and thinking about the fact that I have no makeup on and barely ran a comb through my hair before I left home. I don’t come to the gym to meet men; I come to try and get my cholesterol under control and increase my stamina.

I might have to rethink all of that.

I’ll meditate on it.
