Most mixed martial arts fans, obviously, know about British fighter Rosi Sexton for her exploits in the cage. She maintains a 9-1 professional record with her only loss being to Gina Carano.
But there's a lot more to Sexton than her fists and submission abilities â€“ she holds black belts in both jiu-jitsu and Tae Kwon Do.
Sexton also has quite the academic resume, as well. She has a maths degree from Cambridge University and a PhD in theoretical computer science from Manchester. She is also a fourth year student in osteopathy at Oxford Brookes University.
In short, there's a lot of brains to go with her brawn.
