For one thing you're deflecting my point. There's a few possible mechanisms which could account for that. The body may well adapt to the process of drinking large amounts of olive oil. ultimately that is just a distraction, and surely the priority is to analyse specifically green blobs. Anyone who has been at gallbladder surgery or postmortems could sift out the likely Gallstones and then the rest could be analysed. of course some of the objects will be genuine Gallstones - but that's not the point I'm making.
