I tell my wife that surfing is my only clean vice, the only one that inspires me to get in shape.
When i come home from fishing it is often drunk and smelling of bait.
When I come home from golfing it is often drunk and broke (I suck at golf and gambling).
When I come home from surf I am glowing and stoked.
I always need my outdoors time, that has been a feature of my life forever. She is not a water person, so the time spent at the beach is not a problem for her, but she figures every time I paddle out I am taking a massive risk with my life. I haven't been successful in telling her that while it is dangerous, it is much more dangerous to be fat and out of shape.
