Which is a little different from what I have been feeling.
It is a big number - the Big 5-0.
The scary thing is that it seems like it was just the other day when I was turning 30. Twenty years later and I have three children, one turning 20 in June.
Where does the time go. It is a sobering moment to look back over five decades of one's life.
I cannot even begin to imagine how Madeline Anderson felt this week when she turned 110, making her the oldest living New Zealander.
The first thing I noticed about her when I saw her photo and the interview on television was how young she looked. She could have easily passed for a sprightly 80-year-old. The second thing that struck me was how at peace with herself she seemed.
What a feeling to have lived such a long life and be so contented.
She was asked if she had any secrets to a long life and even her answer was refreshing in its honesty.
"I'm afraid not. It just happened, to my surprise."
At the end of the day it is just a number and all that really matters is that you make the most of life and take all the opportunities before you.
I suppose the main thing is that life begins whenever you start living it to the fullest.
