Hello to my Coxettes, it’s your gorgeous, adored Prof Brian Cox here, and if i’m honest at this moment in time i’m slightly anxious & distracted. But not sweating like common folk…. Why? Because i’m writing this (due to contractual obligations) in a taxi as it wings its way to Heathrow Airport so I can catch a flight off to sunnier climbs. Anyway, i’ve been inundated with tens of emails, perfumed-notelets and text messages, which I was hoping wouldn’t need answering. But i’m told they do or else I wont get paid! And even a megastar scientist and TV icon with beautiful hair and teeth needs paying. Keeping on top of my youthful looks doesn’t come cheap I can tell you… Anyway i’m digressing as I’m driven past my favourite hair gel emporium, Harrods…. You’ve been asking in your droves the same question; “What is the Autumn Equinox, and why do we bother having one as no-one apart from scientists know what it is?” Ok i’ll get this done as quick as possible and apologies for any speling misbakes (the road is rather bumby)… The reason we have Autumn Equinox every year, around late September, is all to do with cavemen and horses… The name equinox is latin, or greek, or perhaps french, for horny horse and legend has it that the Autumn Equinox celebrates a day when horses with horns were first seen frolicking amongst the fallen leaves whilst our cave dwelling forebears searched for conkers. It is said that our ancient hirsute ancestors quickly invented bows and arrows and hunted and ate these horned horses (sometimes called Unicorns) to extinction… So there you have it, if we hadn’t rid the World of these horses we wouldn’t be celebrating now. Or have my little pony. Anyway I must dash off as i’m fast approaching terminal five and can see my holiday chums, Joey Essex, Michael & Tina McIntyre OBE and Carol Vorderman waving to me…. See you soon, and keep the faith (by buying some of my merchandise). Ta ta, Prof Brian Cox.
