We also lose consciousness every night when we sleep.

  I think it's bizarre that we all collectively cease consciousness around the same time every day as everyone around us. We all become willingly helpless for hours with no protection from any danger every day. It's ridiculous.

    Teens typically stay up later than parents who stay up later than grandparents. And babies tend to use a 2-3 hour feed cycle which necessitates mom at the minimum to be somewhat awake. There seems to be evolutionary reasons for this (probably to prevent predation). Interesting some schools and I think California in general has introduced a later start time for teens because of this biology. So it is staggered in general.
