TxRobin, interesting observation and this would indicate we are a special rare group.
On the other hand, Erika's observation about the emergency room could be a more objective measure and would indicate while we are still a minority, we are not necessarily rare in the population.
I thought all this was very interesting, and I know it doesn't change a thing about how we feel for me nor anyone else on this forum. It's just one of those questions that I've thought about often, and as many of the ladies said, one that there probably isn't any way to obtain a reasonably accurate answer.
