Changes in the size of population , age and race
Most deaths occur to people 75 years and older
Id say it would be all of the above. if you think about it our bodies mentally and physically need to rest so they can be "charged" and ready for theday. if you dont sleep you will be drowsy and not to be able to focus on any of the options
Most school have clubs. Some clubs don't have much moving around at all. For example I'm in an art club and a gamers club, both of those do not have a lot of moving around. Hope this helps.☺
