Fyodor Nesterchuk from the Ukrainian town of Kamen-Kashirsky hasn't slept in more than twenty years. Doctors say there's nothing wrong with him but they have no clue as to why Fyodor can't get any shuteye. From Ananova:
"I used to read boring scientific periodicals in the hope they would send me to sleep. But as soon as I felt my eyes getting droopy and put the magazine down, I would find myself wide awake again. I thought it would just be a phase but its gone on for over 20 years now and I've simply had to get used to it.
"Now when everyone else sleeps I get stuck into a good book," said Nesterchuk.
