While doing educational shows, we have talked to many people from Africa and South East Asia who have told us that the biggest reason for carrying their kids on their shoulders was to avoid having one "go lost". Not to tigers or lions, but to snakes.
I've read that a 16' african rock python was found with a 160 lb gazelle inside of it.
A lot of people in South East Asia are small boned, and light weight compared to the average European.
If these pictures are real, which they very likely are, then I do feel sorry for the persons family, that these pictures get circulated in offices across the world as much as they do.
