And Jinwoo also has no limiys he will level up for ever and seing that he's immoryal thats an eternity of leveling up while Goku keeps breaking thru his limiys he still has a shelf life of aging and ultimately dying from old age he wont look it but feel it

Jinwoo is practocly immortal Goku isn't he ages slower than humans but he ages and will someday die while Jinwoo will li e for ever capable of even reviving himself if someone manages to kill him
