If you go directly to a windowless room, with pizza and a lecture, straight from pilates, you will sleep
Add to it:
If you wake up at 7am, go to pilates and then a more thorough workout in the gym (without eating), and then give blood, even getting food and going to work will not prevent you from staring at the screen without focusing for an hour or more
Giving blood was interesting. First time. I didn't realize it was so political.
