Now I'm giving up a little in the week-to-week tournaments but reaping the benefits in the majors.

My dad said: 'It looks like you'll be world No.1 in a few hours and I wanted to be the first to say congratulations.

I'm 37, I'm pretty fit and feel I have another eight years left - which means there's 32 Majors still to go at.

Golf is played between the ears and if you are not 100 percent focused on what you are trying to do, then people will go past you no matter who you are.

In my case what happened next in 1999 was that I fell apart over that back nine. When I saw I was in genuine contention that year I felt like throwing up. That remains probably the most nervous I've ever been on a golf course.

I'm a golfer - not an athlete.

I'm heavier, but with muscle rather than flab. It's a massive difference. It means I don't get as tired sometimes and it means that I'm hitting the ball a lot farther, about 15 yards more with my driver.
