Dwight: As to the theory no comment. As to Mr. Collins comment, I say,
"life-expectancy at birth perhaps. But when I look at my family tree
the length of recorded life spans of those who managed to procreate, I
see spans
that often reached 60, 70 and even 80. And one maternal line that
repeatedly reached the century mark even in the 1800's. Even 100 years
ago, I suspect one in 20 live births didn't get past the three month
mark. Perhaps my ancestors were not your ancestors;-)"
