Generally interesting, but I have a quibble with this:
In the text here, you say
>>Walker outright fakes data to support his “sleep epidemic” argument. The data on sleep duration Walker presents on the graph below simply does not exist:
I went to your link to see the proof that it does not exist. Pretty extraordinary claim. Difficult to prove a negative and all. Figured I would find something solid. Other than two studies with evidence that contradicts Walker’s general claim with a few specific examples, here’s what you had:
>>I have not been able to find any data that would support the sleep duration numbers Walker provides in the book and it appears that they were simply made up.
You can check this out for yourself. Search PubMed or Google Scholar for “sleep deprivation cancer risk.” Plenty of studies come up, but the vast majority find little-no link. The biggest hazard ratio I could find was 1.6, which is not a doubled cancer risk. Note also that Walker has actually retracted his “WHO has declared a sleep epidemic claim,” so we have a concrete example of the guy making stuff up.
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.

I think that speaks for itself.

Yep
He didn’t have a source in the book.
