I’ve been sleeping solid, but yesterday and today (so far) it’s just been impossible to keep my eyes open. What’s up? I’ve been exercising but in the low half of the spectrum — 5k rows, 6k runs, not the 10ks I used to do. Sleep’s actually been solid, even though it’s been hot. So why am I wiped out?

This might just be a matter of grabbing a nap today. We’ll see if I can knock this out.
