Did not link sources because I view this from my phone. (I am sure you can find multiple things on the net). I have hard copies as well.
However by all means get it if you want. I should not have said don't in caps. Furthermore the reason it may or may not be needed is an underlying factor that was never caught in time. Gallbladders are simple and the cells shed and renew at pace faster than other organs. Not going to go into much more as I do not want to direct the attention elsewhere. But I will stand by my personal, and my mentors knowledge.
I hope the best for you Jamas.
