the reason you were able to read more and do more activities in a day when you were a kid than you do as an adult isn’t because you got stupider, it’s because as a child you generally had your base needs taken care of and your schedule provided to you, so you didn’t have to use as much of your mental and physical energy on planning, life maintenance (ie food and administrative tasks), and general executive function. of course you could focus on reading a novel in two days, somebody else made your lunches and you never thought about phone bills and you didn’t even have to decide for yourself when to take a bath. c’mon
