We need to talk about Rudolph: sex, drugs and aerodynamic reindeer

Ever since Rudolph first starred in a 1939 story, we've been getting him all wrong. Or should I say her? Let's look at the science behind the world's favourite reindeer

It is coming up to Santa's busy time. Last minute preparations are being made, lists are being checked and double checked, routes are being analysed and optimised. Elves will be working overtime to put the finishing touches to their orders. But please spare a thought for Rudolph and the team of reindeer called on to drag tons of presents over thousands of miles in the most appalling weather.

It's worst for Rudolph, of course. The world's most renowned reindeer has to put up with all the name-calling and laughter from fellow reindeer. Not only that, but ever since he first came to prominence in a 1939 story written by Robert May, followed by real fame a decade later with Gene Autry's hit song Rudolph the Red-nosed Reindeer, we've been getting Rudolph completely wrong.
