but by way of this wonderful injection of variability as to preferences for when people sleep maybe there are some people who are going to bed at 8:00 p.m. and there are other people and they're waking up at 4: a.m. there are other people who go to bed at midnight and wake up at 8:00 a.m. so then think about that at some point what you've done is that there will always be someone or collection of people awake until midnight and then will always be a collection of people who are awake starting at 4:00 a.m. so as an individual everyone gets their 8-hour opportunity but as a collective as a clan you are you've reduced your vulnerability down by 50% because Mother Nature injected the variability by way of genetics of chronotype to distribute that and lessen the burden
