Scant sleep

Lack of sleep kills brain cells - at least in mice.  That's what was found in a new study from the University of Pennsylvania and Peking University.

"The researchers limited the test mice to four to five hours of sleep over each 24-hour time period. After just three days of sleep deprivation the mice experienced a 25% loss of LCs in a particular section of the brain stem."

More research is needed to confirm that this happens to humans as well, but it seems likely.  Maybe it would be good to take seriously the need for enough sleep.  We all need all our brain cells.
