Data tells the truth, I learned that a long time ago (in 2014, when I wrote this thing) when I started tracking my sleep. I’ve been doing that on and off over the years, and I’m doing it again, using the Oura ring this time. If it wasn’t for that, I’d be certain I’d slept bad the past few nights, because I’m exhausted. But no, it’s something else, and a good reason as any to stop and contemplate.
