I beleive it, like some people said, in that country they are not large people. Some may get tall but not women. a 5 foot tall person at about 80 pounds could be a snake meal. I think you are all fooling yourselves when you think large snakes can't eat us because of our shoulders. Maybe a good 6'5" man doesn't have anything to worry about but I know for a fact that I would be an easy snake meal because of the width of my shoulders being abnormally narrow. Not to mention your shoulders WILL fold together to be eaten...
Snakes? I just like to teraform!
