I'm no expert but I thought that the whole 8 hour a night thing was not true, at least not for everyone. If I force myself to get 8 hours of sleep, by forcing myself to stay in bed after I wake up, I get a headache. If I let myself wake up on its own without an alarm, it averages around 6.5 hours. If I get below that, then at some point I will sleep more than the 6.5 hours, and maybe even 8 hours.

So from personal experience it seems like some of the things in this article do not mesh well with personal experience. I'm just confused at this point as to what to do. Am I suppose to stay sleeping for 8 hours even though I am awake? If for some reason I can't sleep at night and get less hours of sleep than expected, am I suppose to call in late to work and miss my morning meetings? You want to do the right thing here but getting 8 hours of sleep for some people just seems unpractical and there must be countless people who never get 8 hours and live long fruitful lives (I have no evidence for this but it seems like it would be true due to me not remembering anyone who told me they get 8 hours of sleep). I guess I require more evidence that 8 hours is what everyone should be getting. If maybe some people need 8 and others do not, then maybe they need to word it that way.
