Thank you so much for this article.

I read his book and one of the points he made was you could never "make up" missing sleep.

For example, if you pulled an all nighter, you couldn't make it up the next few days if you slept more. Basically the health effects of missing a day of sleep would affect you for the rest of your life.

That was a quite shocking. Were you able to find any information on whether he was exaggerating this?
