I scuba dive... funny story....
Around Christmas time I was scuba diving with a dive shop in the Caribbean and I was paired up with an Irish guy from Dublin (total coincidence). When I told him there was a remote possibility (now THE possibility) that I'd be living in Dublin he told me to get in touch to do some diving. I miiight do that, but it's got to be freeeeaking cold there.
Actually, the waters off of Ireland are quite warm due to the Gulf Stream - the same reason why they have a nice climate instead of being on a par with northern Newfoundland and Labrador, whom they share latitude with. If you check it out on a map, if they didn't have the gulf stream there would be lots of snow and cold weather instead of the rain and mild conditions they enjoy. Cheers,
