Tired and back on dry land but I had the time of my life!
The lifeguard at the pool looked at me with a very confused look when I was putting the tail on and we explained him that it might look a bit weird, and that it will become a whole lot weirder :P
When I got into the water it was the first time that I had my legs "strapped together" so it was quite an experience, but it was very easy to swim in it!
The faces of people and specially of kids whispering: "Look a mermaid!" "She has a tail... - No that's a fin!"
Swimming itself.. The way you feel it moves in the water is an amazing feel and the colours (I picked Sirene) are absolutely beautiful under water!
My breathing wasn't too much of a problem, tho I have to say I'm VERY glad I quit smoking back in january or I'm sure it would have been worse :P

My hubby being my "bodyguard", we had alot of fun in the water today and I'm ready for a nap now lol
We'll go again soon and keep all this exercise up!
