Much has been written lately about "awe walks," meditative strolls in which you intentionally turn your attention outward.

Such walks are easy to do if you can walk and see well, which begs two questions: 

Does walking regularly improve vision? And, does corrected vision improve walking?

With our masks (mostly) gone, we are all ready to show the world our smiles! And new research suggests that all that smiling may make it easier for us to move.

While there is little objective evidence to prove that smiling animals are expressing emotion, we know one thing for certain. They are sure to make us grin!

Here's a healthy dose of zany zoology that will keep you (and everyone around you) smiling -- and maybe even walking a little lighter.

Just as there are two sides to every coin, there are two smiles to every face. 

What is the difference between a voluntary and an emotional smile? 

And what impact does either have on our ability to move?
