What if you could just look at someone’s face and tell how fast his or her heart is beating?
The question isn’t as far-fetched as you might think. The movement of our beating heart inside our chest can in fact reveal itself on the surface of the skin, albeit too faintly for our eyes to see. But as you can see in this video, it’s not too faint for a computer (fast forward to 1:25 and 3:18):

And it’s worked: In less than 10 years, the rate of SIDS deaths dropped by more than half.
But with this drop came an upsurge of brachycephaly – a “positional head shape deformity” characterized by a gradual flattening of the back of an infant’s head from resting on a firm or semi-firm mattress. …
