It’s Valentine’s Day, which means the heart is in the spotlight for the next few days. But you know what? The heart deserves year-round appreciation. Nah, not the one you’d see on a playing card or a love note. The MUSCLE. This thing beats like 115,000 times a day (no, really), and pumps over 2,000 gallons of blood in that time. Pretty hard worker wouldn’t you say? Anyways, whether or not you appreciate your myocardium (Oh, you didn’t think we could get sciency here? Think again.), you’ll definitely appreciate these tunes. Crank the speaker, hit play, and let the beat do its thing.


Neil Young with "Heart of Gold”

The average adult human heart weighs 300-400g. The current price of gold is $50.56/g. You do the math.

Okay fine, we’ll do it: the average adult human “heart of gold” would be worth about $15,168-$20,224 or about 1,500 pairs of Knockarounds. Hey, anything can be currency if you think about it the right way.


Gym Class Heroes feat. Adam Levine with “Stereo Hearts”

According to a study in European Heart Journal, stereos and hearts might make a decent team! It’s probably no surprise, but apparently music can energize, calm, or bring back past memories, which can lead to a slight improvement in heart health. Sure, it’s no “good diet and exercise,” but it’s somethin’!


Bruce Springsteen with "Hungry Heart"

While it’s not the most traditional cut of meat, the hearts from certain animals can actually pack a pretty nutrient-rich punch! For example, beef heart has a higher amount of protein, thiamine, folate, selenium, phosphorus, zinc, CoQ10 and several B vitamins (These things are good for you. Trust us, we sell sunglasses.) than the standard cut of steak or ground beef. And it’s usually less expensive. Probably because no one buys it. Maybe we should order some for our next office party.


Kanye West with "Heartless”

Despite what you might think, not every animal needs a heart to survive. Jellyfish, flatworms, corals, polyps, starfish, sponges, sea anemones, sea lilies, and sea cucumbers (probably not available at your local grocer) all do just fine without one!


Bonnie Tyler with "Total Eclipse of the Heart"

The next total solar eclipse in North America will be on April 8, 2024. Does that mean technically we’ll all be having a total eclipse of the heart?

*Disclaimer: while our shades are great for blocking harmful UV rays, you should not use them to look directly at an eclipse. That won’t do you any good. No good.


Sia with "Elastic Heart"

Having an elastic heart is important to your health. If your heart becomes too stiff (which is caused by a lack of exercise), you won’t be able to pump blood as effectively. Luckily you can get that sucker back into stretchy shape—you just gotta get it moving!


UB40 with "Don’t Break My Heart"

Next time your boo hits the road and you’re feeling too sad for work, tell your boss you’re suffering from stress cardiomyopathy. Yes, broken heart syndrome is a real thing, and it can be brought on by stress and extreme emotion, sometimes leading to actual chest pain and shortness of breath. Love hurts!


Pat Benatar with "Heartbreaker”

Other words for broken heart syndrome include takotsubo cardiomyopathy and apical ballooning syndrome. For some odd reason those just sound a little worse, wouldn’t you say?


Broods with "Heartlines"

If you took all of the blood vessels out of an average adult and laid them in a straight line, that line would be about 100,000 MILES LONG. For a pump the size of a fist, the heart sure can send blood a long way!


Mötley Crüe with “Kickstart My Heart”


By sending an electrical pulse through a heart, a defibrillator can restore a normal heartbeat from an uneven rhythm, and even restart a heart that has stopped. How shocking!


BONUS: Heart with "What About Love"

Wait, did you think we were going to make this all mushy-gushy, lovey-dovey because it’s Valentine’s Day?
