INCEPTION EXPLAINED¿
Hey i recently watched inception again and i have done doubts which I hope someone will clarify
In the ending it was shown that saito has spent years in the limbo and is old so cobb finds him and reminds him it is a dream and they have to die to enter reality which happens. My doubt is why did he attend so much time in the limbo in the first place i mean when he dies in the level 1 he knows that he will enter limbo and since they are heavily sedated just dying won't work so he will need a kick( fall) to get back to previous level so why did he wait so many years that his perception of reality and dream deteriorates which was shown in the tragic backstory of cobb and mal where they spent so much time in limbo cuz they were exploring deep layers .Can someone explain this¿
