I don't believe it to be possible for every human to over come the need for sleep, but as transcript you posted had the man that didn't need sleep for almost or over now 12,000 days. That is pretty fucking mad is it not? Like, not sleeping for 32 YEARS! lol... but yea, maybe it is possible for some, to not depend on sleep for their bodies general well being, although the number of people in the world that could go without sleep for a decade or more (or triple o_O) must be pretty small I would think?
People in the military don't have the choice to sleep I would assume, not that I take much interest in any armed forces apart from FPS (my hearts beatin', my hands are shakin', but I'm STILL shooting and I'm still gettin' them headshots, it's like BOOM HEAADSHOT!). When it's stay awake, or have the chance to be gunned down or casually bombed, it's maybe not such a good idea to get some sleep.
I find if I sleep to much then I find I'm less motivated when I am awake and it actually takes me alot longer to feel awake and generally be feeling like I'm ready to start the day. I get around 6 to 8 a night which I find to be premium.
..wo, when did I start using words like premium :wtf:
