Marmite - hmmm
Not so long ago my development group office had a small kitchen area to make tea and coffee. It also contained toaster, bread and catering sized jars of Marmite. Marmite, if you are unaware is fortified with folic acid and pretty well all the female staff slathered their toast with Marmite. In retrospect it is no surprise that most of the women ended up on maternity leave within a few months of the Marmite becoming available. Just coincidence perhaps?
