Multiple people asked him for a source and he never provided one
The dad is INCREDIBLY divergent from all other data we have. Literally all other data people sleep around 7 hours maybe more maybe less while his data shows almost 9 hours of sleep on average.
Given these three, and the fact that he did literally alter a graph in one other place in the book, I’m pretty sure he just faked this data. If you manage to find the source, I’ll edit the posts and will apologize to Walker.
Yep
He didn’t have a source in the book.
