polyphasic sleep

In an early mention of systematic napping as a lifestyle, Buckminster Fuller advocated his "Dymaxion Sleep," a regimen consisting of 30 minute naps every six hours, which he said he'd followed for two years. The short article about Fuller's sleep in TIME in 1943 also refers to such a schedule as "intermittent sleeping", and it notes:

"Eventually he had to quit because his schedule conflicted with that of his business associates, who insisted on sleeping like other men."

I'd love to try polyphasic sleep sometime. Also, Buckminster Fuller is awesome and Time magazine used to be good.
