Observation of Kids at The Tinkers School

I am not one for poking fun at folks with disabilities but I have been observing a startling number of kids that look abnormal at the little tinkers school. Kids with obvious genetic problems, gigantic ears and funny eyes, a little girl who looks like a fat old woman of 50, I am shocked by it and was wondering what the cause could be, too many agro-chemicals in the water?, perhap, or radon gas from the granite?, possibly, but one comment from another Brit probably summed it up, more than likely in-breeding, an insular mountain village does have its drawbacks and one is the limited availability of women, so marrying your cousin is the answer, but your ancestors pay the price for it.
