Currently about two thirds through this. I agree that it's a great read, quite fascinating actually. Interestingly, he's conducted similar tests measuring a whole range of properties including; response, recovery, memory, health on hundreds of people and he draws the same conclusion as the article. It's certainly made me more aware of my own sleep habits. Highly recommended reading.

Still waiting for an answer from Matthew Walker on his contrasting view from William Dement about Sleep Debt being unable to be paid back.

I loved the book, but I know so many functional adults living their entire life underslept, that I think it must miss compensating mechanisms.

I like this book, but not a lot of practica advice. A good compendium is The Sleep Solution by Chris Winter.
