I decided to prove I was over my sinus infection yesterday by going out and doing four hours of yard work. Even better, I have a brand new hedge trimmer that's tiny and lightweight, so I could pretend I was swinging around a heavy tool but not get overworked.
First, I'm not over the sinus infection.
Second, no matter how lightweight your hedge trimmer is, swinging it around for four hours after not doing that work all year WILL lead to screaming muscle and back pain.
This has been your lesson for the day.
