If life were a game, not getting shot or run over is like surviving against the mobs chaotically spread over the map and not getting poisoned is like surviving the hostile environment. Once you get through that from age 14 (when tutorial ends) through late 30s you get to deal with the real bosses: non-injury. In normal mode you have to fight just one, in realisitic mode you can end up fighting both. But at least you're not getting shot at anymore.
