I seem less tired when I bike to work, despite consuming more energy.
Speaking of consuming, I was worn out Thursday, and haven't biked since; a week later, my intake has dropped back to normal levels, and I'm ... tired. Very tired. Leaving work early tired. Tired on the order that it's been a profoundly slow day for everyone else in my building.
Should this happen?
Other oddness includes finding out that running up 4 flights of stairs is far easier than walking up them.
