@Kingo the Sixth

Just correcting you a bit here. One For All doesn't intrinsically have that risk. It's just that due to the accumulation of power over a LONG time, if the body of the owner of One For All isn't tough enough, it can end up causing serious damage, as the quirk will continously grow more powerful (Wielders of One For All can draw upon the powers of previous wielders of the ability, though All Might has not shown any such developments). Past users of One For All don't appear to have had that trouble, including All Might. It's more just Deku can't handle 100% yet, and All Might had that injury to worry about.

As for Gai, all Ninja have the 8 Gates, which are a part of the 361 Tenketsu that make up one's chakra pathway system. Specifically, the 8 Gates are limiters on the flow of Chakra. This is why opening all eight gates is typically lethal: The user can't survive so much Chakra flowing through them. Also of note: Gai and Lee are not the only ones to be able to open some of the Eight Gates. Kakashi actually has knowledge on how to open at least the first gate, as he demonstrates in Chapter 93.
