>>>awww life is too short to spend it sleeping! I suggest polyphasic sleep - you can gain 2 to 5 hours of awake time per day without feeling tired IF you do it right. It can take a little bit to get used to it - but well worth the effort.

>Well true of course - but who wants to waste 1/3 of their life sleeping? haha. I mean look at it this way - if you sleep 5 hours instead 8 from age 18 to 65, ..lets see that's 3 hours a day times 7 days a week times 365 days a year..thats 1095 hours per year - or and extra 45.625 days per year you're awake. 65-18 = 47years times 45.625 days thats 2144.375 days! ..so that's almost an extra 6 full years of life you just gained! Orrrr if you were using that 1095 yearly hours as billable hours to do work - hey you just added a big chunk of bread to your income.

The evidence is pretty strong that sleep is when your brain stores memories for the long term. Pretty sure there's also some cell repair happening in sleep. Looks like there's evidence that getting enough sleep makes you live longer, too, so your math may not be right: http://longevity.about.com/od/sleephealthandaging/a/sleep_duration.htm.
