Dan Aspey claims he can do well on 5 hours of sleep, and then makes a further claim that any other adult (he recommends not trying to do serious sleep reduction until you’re past 23) can also do well on 5 hours. To judge by a fast look at the comments, rather few of his readers are trying this, let alone succeeding at it.
Do you have any information about whether Aspey’s results generalize?

I am under the impression that nearly anybody who talks about sleep is guilty of Generalizing from One Example.
Not really.
