take diving lessons

My niece took diving lessons and got her PADI certificate or whatever that is called (license?). She told us about her diving vacations and the fun it was. We watched the videos. So my husband and I want to do it too. The closest I got so far is snorkeling (lol). Hey, I felt like a child again last summer, close to the shore, watching the fish under the water, and feeling soooo relaxed and happy. But first, I’ve got to lose some weight and I am not doing anything about that.
