Is anyone else captivated by this series? I was watching tonight's episode on Channel 5 and one thing particularly intrigued me. After a discussion on how the impact of the moon on tides probably led to the evolution of quadrupeds (animal's with four limbs, if you weren't paying attention!), it then discussed if the moon had any impact on the menstruation cycle. The expert's view was that it didn't, or that no studies had shown this to be the case. I somehow think intuitively that it does. As menstruation cycles align more or less with the cycles of the moon and the impact that it probably had on the development of limbs it must have an impact on the smaller issue of menstruation? I'd be interested to know if anyone else wondered about this, or any comments on the fascinating series in general.
