Thank you for doing the math on this one, Sasha!

It's been one of my favorite observations for years

That's when I noted that the law was killing more than it was saving, if you counted the life times wasted behind the wheel... but you said it well, on the net for all to see. Thanks again.

This is not to fail to appreciate your many more profound observations that you are kind enough to share with us...

Keep Shinin'!
