My first book, In Shock, is on sale for only $2.99 the month of February. Given…(gestures vaguely) all of this… it’s a great time to read about the essential role of compassion in healing and also get ready for After Shock, coming in June. #medsky

ICE has now carried out two summary executions of innocent people in the streets of an American city. If you work for ICE, there's no denying that's the mission you're supporting now. You don't get to claim in one year or ten or twenty that you didn't know what ICE was doing. You're complicit.

I've always thought that the whole "natural immunity is the best way to protect people" thing was a bit like saying "getting pregnant is the best form of birth control." Anyway, cool to see it's better for the immune system to see vaccine before virus from an effectiveness standpoint too.

RFK Jr’s gobbledygook is probably confusing for a lot of people. He talks about kids who have been vaccinated having less brightness in their eyes or having “mitochondrial challenges.” What he ignores is their greater likelihood of survival, as evidenced by any modern cemetery.

Plastic pellets are often mistaken for fish eggs by marine animals, who eat them. Ingesting plastic can be harmful on its own but, as Prof Mudge explains, plastic readily absorbs pollutants, exposing fish who eat them to those chemicals, which may be, in turn, passed to people who eat the fish.
