... Martial arts obviously. I would love to know besides your skill in your martial art what other things do you have expertise in perhaps having extending from your MA or been derived from your work or formal study, perhaps through extensive experience or as a hobby or active interest? I am aware of quite a few experts and those with notable experience in a number of areas on the forum and but I would be very interested to know just how broad a range of expertise there is here. Thank you for sharing.
