I discovered a fun activity last night: exercising while drunk. It's really fun!
I went out for some pitchers with coworkers last night and came home around 9:30 feeling tipsy but antsy. I started walking to the store for cigarettes, but it was a nice night and walking felt so good that I just kept going. I walked around my neighborhood at a good clip for 45 minutes before I started to slow down and head for the store; thanks to the alcohol, the stitch in my side seemed like a distant annoyance and I was able to disregard my screaming leg muscles. I came home and was completely worn out, so I went to bed early and got a full night's rest for the first time in weeks.
Aside from the obvious safety issues and the fact that drinking all that beer negates the benefits of walking, I think powerwalking alone half-crocked in the dark is totally brilliant.
