What I said was "There is not a human being alive today who does not have a beating heart."

And here I thought I'd plugged all the loopholes with that word "alive". I pondered that statement for quite awhile before I posted, and the only exception I came up with was human embryos during the first few weeks after conception. Before the heart is developed enough to start beating.   

But then again many would argue that embryos are not human beings yet either ... so, I figured that, in general, my generalization was not really a generalization at all.
