I cannot change a tire and I suspect (although I have not checked) that the men in my life cannot either. That is what money, insurance, and specialized services are for. And, division of labor. No one is supposed to be everything at once and be good at every skill and craft at once. I certainly am not going to lose sleep over the fact that I cannot and will not learn how to change a tire, nor will I select men according to their ability to change tires. I think it is a superficial criterion. Do not even know why this woman speaker chose to talk about tires in the first place.
