I only learned how to swim when I was 14, my friends threw me into the water and said: "you want to live?". Well, and since I'm alive its because it worked, lol. I don't enjoy swimming as much as I should because I don't live close to the sea and I don't like the swimming pool that much.
This summer me and friends are working on a trip for a 1/2 week vacation all together and hopefully I'll add a good swim to my "to do" list.
About how good I am, well that depends if I'm willing to put the effort and concentration (hard to do in a pool), normally I swim just to get myself out of the water, but sometimes (usually in the morning) I'm able to enjoy swimming for a few minutes.
