2 x Ultima Online accounts gone stagnant here; haven't played in the 6 weeks I've been CF'ng. Hundreds of hours over four years that I'll never get back <sigh>.
Personally I don't believe in trying to talk people into making healthy choices, experience has shown me that I will never be successful. Inevitably though, whenever I talk about fitness with someone, my enthusiasm for Crossfit comes out and can be overwhelming :-P However, I believe in being a power of example. When other people see what I'm doing and notice the results I let them know what I'm doing and offer what I can for resources.
What I know can barely fill a thimble compared to some others here but, as the saying goes, someone with 1 day of experience has much to offer someone with no experience!
