we have gone over this ground before johng and you didn't understand then even though I explained it in terms a high school student should understand. and in any case this STILL doesn't prove the green blobs are gallstones, which they have been proven not to be.
re article - go and look up you lazy creature! I am not going to type out the article. I made my own notes and I have given you the substance of it.
for someone who emphasises their own experience you have obtained any Gallstones to find out whether or not they sink or float. you can't even go and read an article yourself.
