Look up Andrew Huberman on YouTube with meditation surely you’ll find something from him. Solid talks on behavior, brain, body etc… just skip through promotions they’re marked on the timeline, can be quite annoying but well worth it for the information he provides
Today I saw a post on a gardening instance self hosted by someone, which contains only one gardening community.
It was small and OP said thanks to the few frequent visitors and traffic from other instances accounts but they are shutting it down since someone posted (I assume) CSAM material on their instance. Doesn’t want to risk it of course so a nice community now has to leave.
