This line from @caseyjohnston.bsky.social newsletter feels depressingly true: "now that Gen Z is mostly adults, it seems like laptops in the classroom were a massive mistake, and all we did was feed $30 billion to tech companies (plus a generation of captive users) who eminently do not need it."

Collagen sits on a throne of lies Or, how the supplement industry took meat garbage and turned it into a 9-billion-dollar business.

@caseyjohnston.bsky.social has me fully collagen blackpilled - it’s Big Beef B2B marketing useless meat garbage to companies selling it as β€œprotein” to people desperate for shortcuts to Gains and Youth www.shesabeast.co/collagen-sit...

you spend years of your life researching WADA/USADA policy about cannabis and sport performance and then you look up and see rich normies just popping the superbanned stuff lol.

I had not heard of peptides, but I saw John Mulaney last night and both he and one of the openers had jokes about peptides and now I see this and what is happening with peptides

it's such a weirdly general term as to be meaningless

nothing good has ever followed 'I don't even need coffee anymore!' Peptides: seriously? Plus: the female strengthspan; why do I want a facelift?; ham dinner in half an hour. This is Link Letter 188!

i can no longer stay silent on the matter of peptides www.shesabeast.co/peptides-not...

someone out there needs to create internet work out & lifestyle content with the framing of β€œhow to get fit to fight fascism” that steps people through exercise & health but also doesn’t succumb down the MAHA/consumerist BS that is all too common on fitness content online

Starting reading @caseyjohnston.bsky.social's A Physical Education on Wednesday night and then I made it to my lifting class for the first time in *two months* on Thursday night. Coincidence?!

Why every fitness influencer is a conservative jagoff They wouldn't be trying to claim it if it weren't actually the key to their ultimate destruction.

short answer, popping and crackling is only a problem if it is painful! if it is, you should get it evaluated, otherwise, joints make noises sometimes :)

Liftoff was life changing for me. I finally found a way to exercise that I didn't quit after 2 weeks!
