Re:Sleep Deprivation can also kill. (Score 1)

There was a DJ for 106.7 KBPI in Denver that now owns the Guiness record for longest continous radio broadcast. He was on air for something like a month and a half. The way they tested to see if he was still sane was to have him sing Kid Rock songs. Once he finished his record, he was off air for about two weeks, slept it off and came back. As far as I know, he suffered no long-term effects, mental or physical (assuming you don't think of two weeks as long term). Of course, he was never quite sane to begin with, to attempt such a record.
