He probably is going to be fine in base nice but once he opens any of the gates im sure it will take a burger toll on his body than it did before he went all eight gates
The only gates he's going to be opening are the gates on the railing that keep him from rolling off his bed and hurting himself in his assisted care home. XD
if naruto keeps his gift from the sage..... i see no reason why he can't completely fix him if he was able to make kakashi a new eye..... year nobody dies in this manga but it is suppose to be a happy go lucky ending i suppose. I foresee him being 100% after jesuto gets dont making his new bff his actual bf, he really wants that sausage.
