"These scientists", almost, they keep dashing all over the place. I think my dad still thinks it strange that my sister and I have moved more than 50 miles away - he and his four brothers and sisters still live within about 10 miles of each other, and almost always have done so, apart from things like National Service. For that matter, most of my cousins live in the same area, although this generation has flown the nest a little bit more - one of us even lives abroad!
