Exercise and tennis was my coping mechanism. When I was fully engaged in something physical my gut was amazing quiet. Not every single time but being in the "zone" shuts off quite a lot of things.
I quit playing tennis, not for UC reasons, but still exercise and have started to learn fencing (!) which is very fun and takes the same concentration as tennis did.
I can understand your "control" idea and won't pass judgement on tattoos. I think they can be beautiful but just not for me. I think it does make a statement about
the person who has them although I'm not sure I can articulate exactly what that is.
