It's not that we simply get old, and memory starts to go, and sleep starts to deteriorate. But those two things actually are significantly interrelated.

If you were not to set an alarm clock, would you sleep past it? If the answer is yes, then there is clearly more sleep that is needed.

I think sleep is probably the neglected stepsister in the health conversation today. I think we've done a good job regarding physical activity and diet, but sleep has remained out there in the cold, and that's surprising to me.

Many business leaders still believe that time on-task equates to productivity. Even in the industrial era of rote factory work, this was untrue. It is a misguided fallacy, and an expensive one, too. Every key facet required for business success will fail when sleep becomes short within an organisation.

My thesis topic was 'The value of a human life.' I asked people a question: 'Suppose you had some risk, a one in a thousand risk of dying - how much would you pay to eliminate it?'

I was so in debt by the end of 'Dust Devil,' having picked up the tab personally for the post-production of the movie, and having no way to recoup because I didn't own the rights to the movie. There was no way I could see any money back on it, so any money spent was just a dead loss.

Death, after all, is the common expectation from birth. Neither heroes nor cowards can escape it.

If you want to connect with people who are in distress and great grief and scared, you need to do it in a certain way. I move kind of slow. I talk kind of slow. I let them know that I respect them.
