When I posted yesterday about the man who died shortly after a sleepwalking escapade in the snow at the Duke estate in 1907, I was unaware of the recent story of the Hayward, Wisconsin man who froze to death after sleepwalking in sub-zero temperatures on January 13. This newest tragedy may have been helped along by Ambien, a drug that the sleepwalker took to help him, well, sleep. Hey, it works!
Apparently there are better, and worse, things to do while sleeping - walking is only the beginning. Take a look here.
