Probably not my brightest move.

I donated blood yesterday afternoon around 2pm. At 6pm I went to the gym with Tom. I had every intention of only providing moral support from a nice stroll of a pace on a treadmill. That lasted for 2 minutes, turned into a 10 minute run, and then a leg work out.
By the end I rationalized it as "zombie training". You never know when you will need to perform a mild workout after losing a pint of blood. I am happy to report that my legs are up to the task.
Surprisingly, I was smart enough to skip the beer with dinner when I got home.
