scientists at the university of wisconsin-madison have discovered that fruit flies with one gene variant only needed 3-4 hours of sleep a day, compared with the normal 10-12 required of other fruit flies. fruit flies are a long way away from humans, but there is a gene homologous in mammals and humans, which means that clever scientists may one day be able to lower our need for sleep as much as 30%. just like fruit flies, there are some people who seem perfectly capable getting by on only 3-4 hours of sleep, which could be a simple genetic difference. the only problem is that the flies manipulated to sleep less decided to die 30% early.
but what is 30% anyway? if we really wanted that much life, people would quit smoking and exercise, and that certainly isn't going to happen - plus you get to stay up all night playing video games and being productive.
