Knowledge is knowing that a tomato is a fruit. Wisdom is knowing not to put it in a fruit salad.
Rugby gave me a confidence. I was quite shy and relatively timid, but it gave me the confidence to be a little bit more out-going and back myself a bit more.
I think my form dipped after the Six Nations in 2007, from the World Cup onwards.
As the summer moves on, there are Saturday nights when I come home and find friends I haven't even been out with sitting up in the hot tub.
The great thing about playing team sport is you win and lose together, and the pain is never as bad when you share it.
The victory is always sweeter... winning things with friends.
