This is one of the key behaviors of champions! I need to set up my red light.

"If we optimize the known factors which improve energy production (red light, short-chain and medium-chain saturated fats, and pregnenolone, for example), to the extent that our metabolism resembles that of a ten year old child, I dont think there is any reason to suppose that we wouldnt have the regenerative, healing abilities which are common at that age. I suspect that both brain growth and remodeling might proceed indefinitely."
