They did a test once that I found interesting, out of a random pic of people they asked them to stay awake as long as they could. Some could only make it to midnight, others could go like three days till they collapsed, but they all only slept for no more the a avg of eight hrs,
kinda interesting, I'll post during the day, but before bed I'll lay here as i am now and spend my time online to unwind, that is before my meds kick In and I pass out, lol
