My back tends to hurt when 1. it's cold, 2. money is tight, and 3. work is busy. On the other hand, my back feels pretty good when 1. it's sunny and hot, 2. money is good, 3. I swim, and 4. I am on vacation.
It's obvious that I need to find a job as lifeguard on some sunny, quiet beach that pays more than six figures, and quick. Wonder if anyone is hiring.
