Next to eating, sleeping is the best thing and as I think about it, there is so much physics involved! As I am very relaxed when I sleep, I never thought about how much my bed supports me. According to Newton's 3rd Law, I actually push down on my bed with the same magnitude that it pushes me with but it we exert a force on each other in opposite direction. When I get into bed at night, I like to jump in my bed, and that applies a stronger force on my bed. This applies to Newton's 2nd Law of Motion because when I apply this greater force onto my bed, my bed has more acceleration until it springs back. Even when doing nothing, physics is always involved.
