Fitness is a curve. You can be Lance Armstrong, or you can be really out of shape at the opposite end. People enter the curve wherever they are and then they can move up the curve, by better nutrition and better exercise.
I'm a better coach now than when I joined Celtic. The longer you stay in any job, the better you become. If you lose your drive, your enthusiasm, your imagination, that experience is no good.
I'm afraid that this is me getting on my high horse now but we have yob television, yob newspapers, and funny enough whereas it was my mum and dad, school, police, church who used to set the standards, now it's tabloids and yob television who set the standards by which people live.
