Retired programmer. "Telling a programmer there's already a library to do X is like telling a songwriter there's already a song about love."--P.Cordell.
When I was 40 I thought I knew how to walk. Then I started some Tai Chi classes.
I did not know how to walk.
It wasn't just the "Tai Chi gait" that I needed, I just needed to be more aware. The classes fell by the wayside, but some things did stick. I can honestly say that the classes have saved me from serious injuries when I trip or fall (which I do). You're probably sitting in your car wrong while driving too, I was.
Timely article for me as I'll soon be rehabilitating after some nasty surgery.
