Bones are ********, i feel on concrete, my bones broke, the concrete din't, also i am able to break a thin bone with my hands, but not a thin concrete bar.

For the falling on concrete part: There's a whole lot of physics behind that which I'm not going to explain here. But basically just because it was a larger amount of concrete, it was less likely to break. Think about how someone skilled in martial arts can split an average cinder block, but couldn't split one the size of a building.

The breaking a small bone part: This is specifically a human bone. Breaking a different animal's bones is completely different.

Your average human can't break a cinderblock. The reason a material arts practioner can do it is because he trained for it. The human body follows a specific law called Wolff's Law, which in its essence means that tissue or bone under stress, will harden to accomodate for said stress. An example would be a tennis player. His swing-arm would have a more dense bone-structure than the arm he doesn't use for swinging. Same for runners - higher density bones than that of an average person.

But to adress the infographic: They make no mention of how the bone is stronger than concrete. Nor how it was tested. I'd assume that they've taken the weight of a femur, applied pressure to said femur, measured its breaking point - and tried scaling it upwards and comparing it to concrete. Which makes for a very loose comparisson.
