The Leeds case sounds a bit disturbing: they used real human fat and "simulated" clothing for an experiment. Seems odd that it was easy to find real human fat, but they had to resort to simulating clothing. I guess in 1963 fast fashion wasn't a thing.
Reminds me of Fight Club where they make the soap from the dumpster outside the liposuction clinic.
I was absolutely positive I was about to read some piece of entrepreneur wank somehow involving the John Wick franchise as a model for some sort of biz dev douchery written by a trust fund jagoff in inappropriately tiny shorts from a beach in Indonesia. Thank you for surprising me with this bit of gruesome lore instead.
