It is writing like this that shames genetical "night owls". A little disclaimer would be nice.
Because as much as I understand that more than 80% of the population is naturally wired to wake up in the morning - the minority of us (including me) is often in their best productive and creative phase between 10pm - 3am.
And it's not because we are "lazy", it's our genetic make-up - if you really read Matthew Walker's book (which you are quoting in this article), you would know that.
