Also for the people who said to just go and spend a few hours in the pool and learn I don't think you realise that it's not that easy to learn when you are older.
Yes it is! Shouldn't take you more than a few lessons, and then you will know that you are a potential asset rather than a potential liability in an emergency, or if you ever see somebody (else) in trouble.
Then one day you will truly be a mighty Duck!
