Unscramble the Blue Letters
So let's now look at sleep deprivation. Huge sectors of socitey are sleep-deprived, and let's look at our sleep-o-meter. So in the 1950s, good data sutgsges that most of us were getting around eight horus of sleep a night. nwodaays, we sleep one and a half to two hours less every night, so we're in the six-and-a-half-hours every-night league. For teenagers, it's wrose, much worse. They need nine hours for full brain performance, and many of them, on a school night, are only getting five hours of sleep. It's simply not enough. If we think about other sectors of society — the aged; if you are aged, then your ability to selep in a single block is somewhat disrupted, and many sleep, again, less than five hours a night.
