Comments of chapter undefined of Reborn to be the strongest God

how a man stronger than even supreme gods can live only for thousands of year? this is why some stories make me itch, think, with great soul power and vitality come from magic, qi etc people have longer lifespans. if our demonlord have super regenative powers how can he have life span. in our world if we have magic and regen powers do you think will people get die in old age. dying with sickness and old age is because our regeneration of cells stop or slow at some point and we have sicknesses like canser or etc.. and all of this get fixed with magic right? this is the question stick in my mind almost at the all isekais and all have the same problem some exempt. i am talking generally not for you author i just have some frustrated with the story i read before coming here. sorry for rambling
