Fast car and fertility

A couple weeks ago I was at my inlaws and my brother in law was giving is theory on "Fast car and fertility"
According something he read somewhere. Men who drives fast cars like these





Produce a higher level of testosterone then say people who drives car like this


So the faster more powerful engine of your car would be related to men's testosterone level and that would increase their manhood therefore making them more fertile!

Well his theory got me thinking. Harry is driving this



And in our 3.5 years of marital bliss, I've been pregnant 4 times (we loss a baby between Sarah and this pregnancy) and 3 of those pregnancy were achieves while I was breastfeeding exclusively!

So if this theory is true, I won't let Harry come close to one of those fast car. I don't think I could handle being more fertile!!!

PS. Hope I did not offend any of you who have fertility problems, this post was just making a point on how silly that theory was, or perhaps is not that silly after all.
