A big call out and thanx to the Swedish
"Infectionists" 🔊🔊
At some point they ought to be called to account, perhaps?
Sadly, they are but the canary in everyone's coalmine. No country will be left behind in the race to chronic diseases and disabling Long C-19

Mortality in Sweden:
The good news: deaths are declining in most age groups >=15. At the same time, causes of death that started rising after 2019 are becoming increasingly dominant across all age groups <15. Most affected are 5-9 and 10-14 year olds.

My concerns about REM Behaviour Disorder and Dopa senescence remain.
My interest in the Vagus Nerve is longstanding... @harryspoelstra.bsky.social gave it my name as a hashtag... Not sure I'm going to be remembered in this light 🤣😂😆

The gut-brain vagal axis governs mesolimbic dopamine dynamics and reward events
Gut-brain vagal signals gate dopamine ensembles, reshaping reward and motivation beyond a brain-centric view.
