Fun guy, I had a friend who needed a liver transplant after taking too much Tylenol. No drinking involved. He was lucky to get a live liver transplant. There are many reasons a liver can be damaged that have nothing to do with alcoholism.

Doug44.1, the Axolotl can regrow its own brain and any of its other body parts, as long as it stays in water. It's quite a fascinating animal. I have two of them.

I know that the liver can rejuvenate however I did not know that it can repair from little left. I find it hard to believe because I have cirrhosis and my doctors have never told me that. my liver is covered in scar tissue which is cirrhosis.

michele, You can have compensated cirrhosis, which means the whole thing can't be covered in scar tissue!

I think it’s called ‘hypertrophy’ As opposed to ‘atrophy’

Player #9809468, we were not meant to eat meat or walk on two legs, but EVOLUTION and EVIL took over, we were given power to choose what we eat and what we do, that's the whole story

William, govt allows addition of cancer and addictive additives to be added to them, dumb people pay big money to govt and give themselves cancer, just like Alcohol, Methadone etc, it's all about money and us being the guinea pigs read up on all of it, THEY DON'T CARE ABOUT US JUST THE MONEY, THE ROOT OF ALL EVIL

Manel, becuz most pain meds have Tylenol/acetaminophen in them as well as other drugs, plus people don't take them as they should, then comes addiction....

Player #1126073, one time I stepped on a lizards 🦎 tail that was in my room when I was 9 now I'm 10 after a few days its tail started to grow back and it's tail was still wiggling. Some of the lizards tail was still there but some was gone. And I also saw the tail that its growing inside the top part of its tail. It was disgusting 😒 😑 😪 😐 🤢🤮
