I like this Tiger Bloc podcast, which is a lefty gun-focused podcast, but this episode focuses on Community Defense Medical. Which everyone should find useful, even if you want nothing to do with firearms.

Convinced me. I'm half way through but when I get on the desktop I'm going to find local training classes. I live in a large 55+ complex and my friends and local park walkers are mostly older, so even if I don't need it as a response to violence it could come in very handy. I know the basics but some hands on training would be wiser. I may have to resort to a fanny pack, though. I have this thing where I need to be hands free.
@Puck I still have to find a Stop The Bleed class, but I'm good on CPR.
I did just order some of these https://www.rescue-essentials.com/israeli-emergency-bandage/ and trying to decide on an IFAK.
Like you said, there are anumber of sutuations and injuries where it could be useful in saving someone's life. Narcan is another that I'm almost certain won't be used on me but could save a life.
