Today I Learned: These Mildly-Interesting Photos Are Proof There Are New Things to Discover Every Day

When it comes to hearts, the blue whale reigns supreme. In fact, a blue whale’s heart is so big, you could swim through its arteries! That’s right, folks – a blue whale’s heart can weigh as much as 1,000 pounds, which is about the size of a small car.

To put it in perspective, a human heart weighs just 8-10 ounces. So if you ever find yourself in the belly of a blue whale (which, let’s be honest, is a highly unlikely scenario), just remember that you’re in the presence of one of the biggest hearts in the animal kingdom. And who knows – maybe that big heart will inspire you to do some big things too. Or, you know, just stick to jogging on the treadmill.
