It is quite interesting how physics can be found in such random parts of your daily life. One such example of this is sleeping. When a person sleeps, they are exerting a force on the bed that they are sleeping on. According to Newton's Third Law, the bed then exerts that same force back on to the person sleeping. In addition to this, gravity holds the person down to the bed, keeping them grounded. When I need to wake up in the morning, I set an alarm on my phone and put my ringer on high. This way, the high frequency pierces through my sleep, and wakes me up. I have never realized just how much physics is in such a simple act!
