Japan Probe reports...
Japanese scientists believe they have found the gene that causes narcolepsy:
It occurs in 1 out of 2,500 individuals in the United States and Europe, but is at least 4 times more frequent in Japanese.
The researchers analyzed the genomes, or DNA, of 222 narcoleptic Japanese and 389 others who did not have that condition, and one gene variant occurred with significant frequency among those with narcolepsy, they wrote in a paper published in Nature Genetics.
So now you know why you see many folks over here sleeping around in public - this pic from the Japan Public Sleeping Returns article.
I do occasionally feel sleepy after lunch. Washing my face with cold water, brushing teeth with mint toothpaste and gargling with strong Listerine usually wakes me back up though ^^;
Do you feel sleeping during the day sometimes? What do you do to stay awake?
