Episode 25: Lying Down is the First Milestone

One major milestone that we learn from infancy is how to lay down. We can see babies sleep in almost any position but as we grow up we seem to lose the ability to do so. As astronauts go into outer space, they return to a state of float and lose the milestones they gained as a child. this includes the milestone of lying down. Without this they lose a level of function that has to be relearned.
