Good Lord, what are we coming to? Soon everyone will have tails. But I do understand that marrying a first cousin is really not risky unless there is a genetic recessive disease in the family.
It's not, unless you keep doing it for generations. For the sake of family honor, though, I feel it necessary to add that nobody in my family has married a first cousin. 2nd cousins, yes. 1st cousins, no. They had their limits.
