This picture is in time with the average heart rate. What you’re hearing is the sound of your blood pumping, which you aren’t normally aware of. This picture tricks your mind into making yourself aware of your heart rate, so you hear it.
IM SCARED
How is that possible..? Heart rates don’t all go at the exact same time an they definitely wouldn’t all go exactly to the beat of the gif, pounding when it hits the ground.. That’d be more of a coincidence…
