Since the start of COVID and not needing to commute, I found myself with time to exercise for the first time in many years. In order to use that time efficiently and avoid injuries that would inevitably come from someone in his late 30's pretending he's in his early 20's, I read a bunch of books around running, biking, strength training and nutrition over the summer.
I try to make myself read some fiction, but I don't feel compelled too often enough, so it doesn't happen much. I end up re-reading Lord of the Rings and Chronicles of Narnia every 2-3 years.
I've been listening to a few Audible books lately about Roman History. A finished a biography of Caesar and a book offering (yet another) set of theories on the fall of the Roman Empire. I'm currently listening to a book about Cicero's life.
For sorta-related-to-work I have a few really niche books I'm reading on Telecom OSS/BSS, network planning and telecom regulation.
I think my favorite author remains GK Chesterton, he has a couple books I try to re-read every so often. It's fascinating how he was writing around 100 years ago, and how around 25% is super old-timey cultural references or things that no one would think today, but how much of it is still pretty relevant. Also, I haven't read anyone better at turning a phrase.
