It does make me wonder. If the average woman in a developed country (such as the U.S. or Great Britain) ages chronologically a bit faster than she does biologically, it makes sense that fertility is the first thing to take a hit - the canary in the coal mine, if you will.
Obviously, I don't think it's that simple. Every body is different and there are many, many reasons why someone would suffer infertility. In my case, the specialist told me I had an "egg quality issue" two years ago. And while ultimately I believe God chose to heal my body and heart, I certainly did pursue health as a means of improving my chances of conceiving successfully (I was a Weight Watchers lifetime member before I got pregnant, and am back on the program now). That was a pretty short time frame, though, and not likely long enough to really turn things around if, in fact, that was the problem (and I have reason to believe that wasn't the whole picture).
The question I ask myself now is, How old am I really? Am I too old for anything? I once thought 42 was horrifically old to be giving birth. Now I kind of laugh at that idea and wonder what the future holds. I sincerely hope to be healthy enough to live long enough to see my own grandchildren.
