Want to know how I know that I'm old, out of shape, spend too much time sitting at my desk and writing, and not enough time exercising? I hurt my back yesterday ... by standing up.

Yep. That's it. Doorbell rang, I stood up to go to the door, and the whole right side of my back seized up. Goodtimes.

It still hurt this morning, so I went out to see my massage therapist to get it worked on just after lunch.

She worked out a lot of the tension, reminded me (as always) that I need to take better care of myself, and I headed home ... so I could write this story that my brain is demanding I write.

Shortly after I got on the freeway, I saw a huge crash happen, entirely because someone was driving like an asshole.

It really shook me up, because just this morning I said to Nolan, "Whenever you go somewhere with your friends, please make sure you are wearing a seatbelt, and never ride with someone who drives like an idiot."

"I do, and don't worry, because my friends aren't idiots."

"I have no reason to doubt you, but there are idiot drivers all over the place, and if one of them decides to crash into you, I want you to be wearing a seatbelt."

"Okay, Wil. Don't worry."

"Sorry, but I'm going to worry, because I'm your parent and that's just my thing," I said.

When I was on the freeway just about an hour ago, I was in the number 2 lane, cruising along with the flow of traffic. I saw that the number 1 lane was slowing down a lot, so I slowed down too, just in case people whipped out of that lane and into mine. It happens all the time, because people drive like assholes.

Sure enough, some asshole was speeding down the number 1 lane, and I don't know if he wasn't paying attention or what, but he whipped around into my lane - about 100 yards in front of me, I suppose - over corrected, spun sideways, and T-boned a van. The van flipped onto its side, and the asshole driver sped into the carpool lane. I'm not sure if he crashed into the wall or hit his brakes, but he stopped and got out of his car. I expected to see a 20 year-old kid, but it was a man in a suit who appeared to be in his late 40s or early 50s.

The van, on its side, was about two car lengths in front of me. I realized that I'd been holding my breath, and my hands were shaking so hard I could hardly grip my steering wheel. Just when I snapped out of it and thought I should get out to help, the door of the van opened and the driver climbed out. I couldn't tell if he was hurt.

I picked up my phone to dial 911, and saw that every car around me was already doing that. I started to get out of my car, and I saw that about six or seven different people had already gotten out and were checking on the people who were involved in the crash. I decided that I'd just be in the way if I stopped, so – very carefully – I drove around the scene of the crash and – very carefully – I drove home. When I got into our house, I immediately called Nolan to reiterate our conversation from this morning.

My hands aren't shaking as violently as before, but now I can't stop thinking that, if I had been less than 15 seconds farther down the freeway, I would have been in the car that was crashed into by the asshole driver.
