"While on Facebook, have you ever come across a posting that tugs at your heartstrings? Photos of adorable abandoned puppies, say, or a story about a cute little girl who didn't get any happy birthday wishes? You instinctively click the 'thumbs-up' or add a comment (Happy birthday!) and maybe even decide to share the posting."

"There are two moments in 'Mary Poppins Returns' when the grown-ups watching really lose it: Dick Van Dyke's arrival and when Angela Lansbury starts singing. Those are playing on a lifetime of heartstrings." 
— Lin-Manuel Miranda, quoted in USA Today, 27 Dec. 2018

Did You Know?
Before a song or movie or heart-shaped card accompanied by a box of chocolates could tug at your heartstrings, the job was more likely to be accomplished by a surgeon: the word heartstring used to refer to a nerve believed to sustain the heart. 
You might recognize the word's second syllable in the term hamstring, which refers to both a group of tendons at the back of the knee and to any of three muscles at the backs of the upper legs. 
It's also apparent in a rare dialect term for the Achilles' tendon: heel string. And in light of these terms, it's not surprising to know that string itself was at one time used independently to refer to cords like tendons and ligaments.
