Being born in a seaside town - Falmouth, in Cornwall - played its part in me being a bit of a sea creature, but it was once I had been taught to swim at my wonderful primary school, Oratia, that I really felt in my element.
When we were young, Mum and Dad would take my sister Margaret and I up to Orewa for the day and - living in the western suburbs of Auckland (yes, I'm a westie chick and proud of it) - we would often go to our west coast beaches too.
And, in our Christmas school holidays, Dad had a mate who allowed us on to privately owned land right on Matai Bay and there, with no one else around, we would pitch our ancient green and white canvas tent and camp there for a week, just being salt-and-sand-covered water babies. Bliss!
These days, when "diva-ing" allows and when it's warm enough, I love going for a swim at Takapuna Beach, and I have had the great good fortune to swim in open ocean when friends have taken me out on their boats. There is nothing like swimming in deep water - the incredible feeling of being very insignificant in the midst of such vastness.
And, a few years ago, I did a five-day surfing school up at Ahipara. I loved it. I didn't manage to stand up until the last wave on the last day, but I didn't care.
Whether lying on the board or trying like a mad thing to stand, I wept with an overwhelming happiness from the magical feeling of being carried on the laughing shoulders of Tangaroa.
