My family has been able to regenerate damaged stuff for as long as I can remember. In 1960, my brother had had his thumb cur off in a car door hinge. It took him about 6 years but a new thumb grew back (It’s a half inch shorter than original but it’s a thumb). About a dozen years ago, he lost a kidney in a car wreck. Five years later, during a cat-scan they found a new kidney. As for myself, I had a heart attack 30 years ago. A 2-in section of heart muscle died. It took 5 years to regrow and come up as fully functioning. In 1974 I breathed some chemical monomer and it formed a plastic film in my lungs (I coughed blood, plastic film and lung tissue for 4 months). My lungs are perfectly normal now.
So regrowing stuff is not unheard of, it’s just rare.
If you do have this ability, don’t let a doctor know or he will want to test you and do biopsies. They biopsied my heart after the damaged part grew back. Damn, that hurt.
