I've got my head fixed on the next part of life. I know there will be an adjusting period of just not being a rugby player for a while, and over that period I'll get my head around what the next challenge involves.

I want to tell mayors, county chiefs and heads of big companies: don't just chase GDP growth; don't chase the biggest profits at the expense of our children and grandchildren and at the cost of sacrificing our ecological environment.
