It’s a work of fiction, but I highly recommend Last of the Amazons by Stephen Pressfield. He does fantastic, heavily researched historical fictions with an abundance of resources at the end to reaearch the history he bases his plots off of.
It’s basically about Eurasian tribes who had horses central to their religious mythos and how they dealt with the Greeks. It’s fantastic.
I was an old school skater all through the hey-day of Tony Hawk, and I also fought Muay Thai for decades. By the time I hit thirty, I was like a case study for orthopedic doctors.
I bit the bullet and accepted I’d boarded until the wheels fell off and I couldn’t keep getting hurt. Picked up a longboard and it’s like my #1 hobby now. Just did 25 miles in sub-freezing temperatures right before we got slammed with the blizzard.
So no more half pipes. Just throw on a death metal album and pack a bunc of joints and cruise.
