An unfortunate reality but at least that means sleep deprivation only needs to happen 1-3 times a week, not every night like I got used to. The difference between 7 hours sleep a night to 8 hours during the midweek days has made the biggest impact on my life. The book discusses that the difference between 7 hours and 8 hours has almost as much an effect on you as that of 5 hours and 7 hours. The last moments before you wake up seem to be the part when the electrical "waves" that happen during REM sleep are at their strongest, but sadly it's that REM cycle particular that almost everyone misses. I'm a night owl forced into a day time job (if given the option I'd happily stay up till 2am), so I struggle with getting to sleep early - but now I've learnt how important it really is I'm much more motivated to force myself to do it.
