[blank_start]The[blank_end] need [blank_start]to[blank_end] sleep [blank_start]is[blank_end] one [blank_start]of[blank_end] [blank_start]the[blank_end] strongest biological urges we have, one [blank_start]of[blank_end] [blank_start]the[blank_end] few [blank_start]that[blank_end] [blank_start]we[blank_end] really can't control; and [blank_start]the[blank_end] fact is, [blank_start]you[blank_end] [blank_start]can[blank_end] die faster [blank_start]from[blank_end] sleep deprivation [blank_start]than[blank_end] food deprivation. So [blank_start]it[blank_end] [blank_start]is[blank_end] time [blank_start]to[blank_end] investigate [blank_start]the[blank_end] science [blank_start]behind[blank_end] [blank_start]this[blank_end] thing [blank_start]that[blank_end] [blank_start]we[blank_end] do [blank_start]for[blank_end] [blank_start]a[blank_end] third [blank_start]of[blank_end] [blank_start]our[blank_end] lives. Even though [blank_start]the[blank_end] average person [blank_start]will[blank_end] spend 25 years [blank_start]of[blank_end] [blank_start]their[blank_end] life asleep, [blank_start]there's[blank_end] no scientific consensus [blank_start]as[blank_end] [blank_start]to[blank_end] why exactly [blank_start]we[blank_end] do [blank_start]it[blank_end]. One thing [blank_start]we[blank_end] know [blank_start]for[blank_end] sure: [blank_start]our[blank_end] brains definitely think [blank_start]that[blank_end] sleep [blank_start]is[blank_end] important.

The [blank_start]need[blank_end] to [blank_start]sleep[blank_end] is one of the [blank_start]strongest[blank_end] [blank_start]biological[blank_end] [blank_start]urges[blank_end] we [blank_start]have[blank_end], one of the [blank_start]few[blank_end] that we [blank_start]really[blank_end] can't [blank_start]control[blank_end]; and the [blank_start]fact[blank_end] is, you can [blank_start]die[blank_end] [blank_start]faster[blank_end] from [blank_start]sleep[blank_end] [blank_start]deprivation[blank_end] than [blank_start]food[blank_end] [blank_start]deprivation[blank_end]. So it is [blank_start]time[blank_end] to [blank_start]investigate[blank_end] the [blank_start]science[blank_end] behind this [blank_start]thing[blank_end] that we [blank_start]do[blank_end] for a [blank_start]third[blank_end] of our [blank_start]lives[blank_end]. [blank_start]Even[blank_end] [blank_start]though[blank_end] the [blank_start]average[blank_end] [blank_start]person[blank_end] will [blank_start]spend[blank_end] [blank_start]25[blank_end] [blank_start]years[blank_end] of their [blank_start]life[blank_end] [blank_start]asleep[blank_end], there's [blank_start]no[blank_end] [blank_start]scientific[blank_end] [blank_start]consensus[blank_end] as to [blank_start]why[blank_end] [blank_start]exactly[blank_end] we [blank_start]do[blank_end] it. [blank_start]One[blank_end] [blank_start]thing[blank_end] we [blank_start]know[blank_end] for [blank_start]sure[blank_end]: our [blank_start]brains[blank_end] [blank_start]definitely[blank_end] [blank_start]think[blank_end] that [blank_start]sleep[blank_end] is [blank_start]important[blank_end].
