Thai Ngoc, a man in Vietnam, claims to have stayed awake for over 40 years. He says that it all started after coming down with a fewer while he was in his 30’s. According to him, he hasn’t been able to sleep a wink since then. He tried both medicine and traditional folk remedies, but nothing worked. Still, doctors who examined him are amazed and say he has no health problems, despite the lack of sleep. Some specialists say the man might not be able to clearly observe the difference between sleep and wakefulness which means he could feel he is merely resting when in actuality he is sleeping.
