Re-picking up hockey in college was the best thing I could have done. Took a while to get good, but now I can play the best sport on the planet, and take a girl ice skating if need be and look like the best one out there! word of warning is that its expensive, and probably the most niche sport of the big ones. Having played all the other big ones , some competitively, none even come close. many years later, its still my passion and am always finding ways to get better at it. it also keeps you in excellent shape as you need to be strong, fast, agile and coordinated to play; its the total package.
Asking others to name some hobbies for you is like saying, "I want to try new food. Can you recommend some?" You'll get 100 different responses from 100 different people.
agreed, and my response is no less biased than someone elses. The merit of this thread is for respondents just as much as the OP though.
