That would be amazing… imagine face planting from a stupid stunt and being like no biggie they’ll grow back. Works for kids and we already know from admittedly gross tumors the human body can grow hair and teeth. Just have to get them in the right place.

Also agree with the other comment to your post… crispr will likely be for the rich. Hell, it probably already is. A cynical view but i don’t sit at that table so who knows.
