You'd think going without sleep for that long may have its drawbacks, but not for the man in central Quang Nam province who has never been ill after decades of insomnia.
His inability to sleep has not only made him famous, but also represents a miraculous phenomenon worthy of scientific study.
Sixty-four-year-old Thai Ngoc, known as Hai Ngoc, said he could not sleep at night after getting a fever in 1973, and has counted infinite numbers of sheep during more than 11,700 consecutive sleepless nights.
"I don't know whether the insomnia has impacted my health or not. But I'm still healthy and can farm normally like others," Ngoc said.

His wife said, "My husband used to sleep well, but these days, even liquor cannot put him down."
