Obviously they don't dissect every part of the liver on 'everybody'
who has died with Gallstones in the gallbladder. The point is that
they have dissected every part of the liver on 'enough' of the people
who have died with Gallstones in the gallbladder to reach a
conclusion which is based on facts. Hundreds of dissections on
internal organs after death have been sufficient to prove a point
with facts.
Study the results and let me know what you find. Maybe the sufficient
facts will not prove anything to you. I don't think the facts are
wrong. I think they should be respected for what they have proven.
Good luck in your search for this particulat proof that you need. I
hope you find the truth.
