My double red eligibility opened up earlier this week — right on schedule, every sixteen weeks, whether the world needs me or not. I didn’t want to look like the guy who watches the schedule too closely, so I waited two days before heading in. Judging by the mood I walked in with, the staff probably wished I’d waited a couple more.

Before I left for OBI in Norman, I had to give our final hockey boy his end-of-season pep talk. I snapped a picture of him before I left so I could pretend I was still there when he actually walked out the door. The picture was taken a half hour too early. I am a scoundrel with no photographic ethics.

The older couple ahead of me at the front desk had arrived early. Fortunately, the staff member recognized my impatience and quickly got me into the screening room. I had a couple of lines I was proud of. When they asked if I’d ever donated under a different name, I said I usually go by Andrew, but sometimes Andy. When they asked if anything had changed since I completed the survey four hours earlier, I said I’d been briefly pregnant but wasn’t anymore. My slap-happiness does not always have good taste.

The screener, it turned out, works at the hockey rink. She has brothers who played out of state and were billeted at houses just like ours. Except the homemade pizza probably wasn’t as good.

Three people got involved once I was set up at the apheresis machine — the vampire machine, as I think of it, since it gives back what it doesn’t need.

The first got me settled in. Heating pad, arm pillow, squeezey toy. She handled the light work so the next person could focus on the vampire-specific functions.

The second was Hannah. I didn’t say Montana, but I thought it. She walked me through a recent FDA rule change: you now squeeze the toy the entire time, not just when blood is leaving your body. Apparently, the change was made to keep things straightforward for everyone. It does more than tickle when the flow reverses, by the way.

The TV had replaced the Power Rangers with American Ninja Warriors. One contestant was clearly training full-time for this at age 52. I thought about thinking something more critical, then remembered I was the guy who drove across town to lie in a chair and squeeze a toy. With the TV failing me, I studied the donor-recipient chart on the wall. My O+ can go to any blood type with a plus sign. I’m basically the Costco of blood.

The third had a paramecium tattoo on her left upper arm and a light blue bandanna. I’m not explaining it further. After the needle came out, she reached for the stretchy wrap and opened a drawer full of colors that would have had me deliberating for several minutes. She chose beige. It was the end of the roll, so I can respect that. But couldn’t I be special just once?

I settled in at the snack table with my Chex Mix and Gatorade, Nutter Butters tucked away to go. With my daughters out of the house now, setting them on the kitchen counter still brings back some fond memories — something to look forward to on their next visit.

So why do I throw two hours away watching things I don’t care about while surrounded by tattoos and piercings? It’s not the T-shirts, though “Get Your Sticks on Route 66” is genuinely good. It might be a little bit of my dad, who donated regularly — except he had hepatitis, which probably disqualifies the hereditary angle. Since he’s not around to ask, it still makes a good story.

When all the other reasons fall away, I’m healthy and able to, and that’s enough. When the cholesterol results show up in the OBI app, I smile and pat myself on the back for something I had no control over

I must like people at least a little. I married one.
