In one of my favorite episodes of Friends, Phoebe embarasses Rachel by running with wild abandon, arms and legs flailing with joy.
Rachel is too self-conscious to be stared at and avoids Phoebe, until one day she decides to try it herself. "This feels great. I feel so free so graceful," Rachel concludes.
There are so many things that are good for us that we don't do, because we are too self-conscious. Simply stretching at work or undulating on a bus would make a world of difference in our physical comfort. Think of it this way. If more of us were willing to enjoy the free movement of childhood on a regular basis, it wouldn't be so weird.
