Or, how I spent my day and learned to love nails in the roadway.
First off, changing tires is no big thing. I had a Volkswagen, I would take tires on and off every 3000 or so miles, except in winter when it was worth the money to let the professional deal with adjusting the valves and/or brakes. But here’s the thing. Even with aluminum rims, SUV tires* are mucho heavier. And I admit I haven’t been doing my situps lately. So, my back was a little sore. But then, Monday is my long run day in my running schedule, due to the vagueries of my job. It would have been far more enjoyable if it hadn’t felt like my spine was slowly grinding into my pelvic bone.
There’s a lesson in there somewhere for you.
*nails in two tires. By the grace of God only one went flat. The other was just a slow leak.
