Chevy Chase. Beyonce. Napoleon. The lunch lady. Bruce Lee. Grumpy Cat. This random assortment of humans (and one animal) all have something in common: hearts. They each have one. February and hearts go together like PB&J (clearly we’re referring to the greatest love story from The Office, Pam Beesly & Jim…) but we’ll let someone else handle the gooey relationship stuff (we’re looking at you, Russell Stover commercial). So while February 14th is a reminder to make plans for your figurative heart, the whole month of February is a good chance to think about taking care of your actual, physical heart. You know, that silent partner that is constantly working to keep you alive. Yeah, we’d say it’s worth showing some love. But you can’t appreciate your heart (or why it’s worth taking care of) without a quick refresher of how it fits into the whole “staying alive” (ah, ah, ah, ah, staying alive, staying alive) scheme.
