Normal, everyday gestures can look really strange when you get down to the bones of it all. Artist in residence Hugh Turvey at the British Institute of Radiology created these digitally altered images using X-ray equipment, colorization and shadow photography.

You can see the intense, unnatural angles at which the bones of the feet are bent in high heels. Dramatically abnormal, this may make you rethink wearing them every day.

Throwing a punch just seems very unwise, even when wearing a padded boxing glove. If you were to pack a powerful enough blow, it’s clear to see how the radius and ulna (bones of the forearm) could easily fracture and break on impact.

This is probably a lovely holiday photo of a family in Paris. Or is a skeletal army making its way through Europe?

I mean, if you really think about it, kissing is just crudely mashing your skull against someone else’s skull, but there’s soft tissue in the way, and this feels nice, I guess? It definitely looks unusual in X-ray form. Humans are weird.
