Steppe by Step (Guardian). "I started wondering if (the 'six degrees of separation' theory) was true today. ... So 35 years on from the original experiment, I decided to test out the urban myth on a world stage: how many steps would it really take to get to someone on the other side of the planet?"
The London-based "city girl" author, Lucy Leveugle, makes it in 9 steps (hey, the world has expanded!) to Purev-Ochir Gungaa, a nomadic herdsman in the middle of the steppes of Outer Mongolia. Amazing.
