We are taking part in this challenge not only because we want to start being a bit healthier, but also to support our sister/daughter and her crew in risking their lives to save lives at sea.  It may not sound like a big challenge to some, but giving up all drinks except water for 10 days will be quite a challenge, especially since I (Lani) have an exam in the middle of it!  No tea to wake me up in the morning, and no celebratory beer when the exam is over!  Any donations, big or small would make it worth our while to do this challenge - and it's going to a great cause.
