As you know, you can’t tickle yourself. But if you are ticklish, anyone else can tickle you. So why is that? Even if you know someone is about to tickle you, it still tickles. Listen as this episode begins with an explanation of how tickling works. http://www.livescience.com/3882-tickle.html Our culture – in fact the whole world lives on schedule of a 7-day week. Yet, the week is a totally artificial, man-made invention. Other ways of measuring time such as days, hours, months and years are related to the sun, the moon, the rotation of the earth and other things – but the week is all just made up. Yet it works so exquisitely well! Imagine life with the week. Your schedule would be a disaster. Here to discuss how the week came into being and why it is so important is  David Henkin, a professor of history at the University of California at Berkley and author of book The Week: A History of the Unnatural Rhythms That Made Us Who We Are (https://amzn.to/3InCDwl) Are you a cat lover?
