I am one of those lucky people who enjoys his work and spends more time than he should either doing work or reseaching new stuff. I can also be found on playing DDO on the Cannith server (Send a tell to "Maetrim" who is my current main)

I am also a keep fit fanatic, doing cross country running and am seriously into [url]http://www.ryushinkan.co.uk/[/url] Karate at this time of my life, training from 4-6 times a week and recently achieved my 1st Dan after 6 years.
