For those who worry constantly about death, we have some good news for you! There's now one less thing to worry about!

Scientists at the University of Illinois at Urbana-Champaign and Washington University in St. Louis have developed a thin, 3D-printed membrane that wraps around a heart and enables it to beat perfectly forever.

First, a scan of the heart is taken. Then, wizardry happens.

The scan is loaded into a 3D printer and bam: Out pops a perfectly-sized membrane that wraps around the heart.

How does it keep the heart beating? Who knows? But we know it's true because of the video below!
