Vladimir Putin barely swings his right arm when he walks. His walk has been called a "swagger," but a group of neurologists says it may be something else: KGB training. (Video via President of Russia)
The study comes from The BMJ's Christmas edition, which features funnier science like why Rudolph's nose is red.
The group ruled out Parkinson's, which can cause "asymmetrically reduced arm swing," because Putin's right hand shows no sign of tremor or muscle weakness. (Video via RT, President of Russia)

Now, we're no experts, but do any other leaders have the walk of a trained killer?
