There are many people who sleep little, but it seems there is also those who never sleeps. For example Ngoc Thai, Vietnamese farmer of more than seventy years since 1973, when at the age of 31 years has been suffering from a mysterious fever, is never able to sleep.

The man underwent countless medical tests and is always under regular monitoring hospital in Da Nang, but the results reconfirm every time a healthy and a perfect state of physical health. With the exception of a liver problem, no bearing on the lack of sleep, and a small right hemisphere of the brain abnormality, slightly more voluminous than the left.

Microsleep. Although Thai Ngoc alive hard days on his farm in Quang Nam, working in the fields, the night still does not sleep. The scientific explanation could be that of microsleep, a break of a few minutes or even seconds throughout the day, imperceptible even to the person, if they were sudden and short blackouts. But it would help the brain to recover energy.
