I didn't start playing till I was almost 17, and since that faithful winter I've picked the game up remarkably quickly, and seem to be somewhat of a natural. In the short time I've been playing I've developed into one of the quickest guys at my club, probably 2nd quickest, just behind a guy that plays/has played for Suffolk, so I've done pretty well. Batting's not come as easy to me, but I'm starting to become far more confident, and have gone from getting 6 straight ducks in my first season to being a more than capable number 7/8.
I say go for it. I'd say I regret not starting earlier, but I wasn't really a big cricket fan until a few years back, so it was just natural progression into playing. Starting to play has allowed Cricket to become my prime passion in my life, and from something I enjoyed watching on TV, to something I am obssessed with and something I spend far too much time watching/playing/thinking about the game. Get stuck in, join a club, it's one of the best things I've ever done, if not the best.
