Must try reading these again! My friends rave about them but I got about 200 pages into the first one and realised that I just didn't have the time to do my PhD and read such a lengthy series of books!
Yeah, I got this when I used to do Thai Boxing/Kickboxing too! But I've just learnt to embrace my geekdom (mainly because I don't give a f**k what other people think of me!)
Mine is a combination of a childhood nickname of Jonah (because I used to be pretty clumsy (I still am, but not to the same extent) and when playing a game of 40k in my local GW managed to break the stores Carnifex, Lictor and Hive Tyrant in one game and somebody said you're such a Jonah because of the character in the Beano/Dandy (still not sure which one) and it just stuck. I like it though, it's cooler than my given name of Michael and even my wife still calls me Jonah! The maul bit got added when I couldn't use just jonah for an e-mail address and was because of Darth Maul from Episode 1 (I was young, what can I say!). Now I just pretend it's about rugby!
