"I have made lots of mistakes in terms of contracts and spending money when I shouldn't have spent mo..." — Jenson Button

You're pulling 4-5G for a lot of the corners around the lap. We build up lactic acid because there are a lot of vibrations in the car, and you have to have strong legs to hit the brake pedal. We need to be fit to do every lap at 100%.

That Monaco crash was quite a big one - I pulled 33g when I hit the wall, which is a lot. It's a weird sensation - like all my skin and flesh was being pulled off my bones.

The only time I think about life beyond F1 is when I contemplate becoming a dad. But there's no way that's going to happen while I'm still racing. To be successful in F1 you need to be very selfish in lots of ways and you're away from home for long periods. That's not the kind of father I want to be.

If someone was making a movie about F1 in the last six months, they wouldn't need to add a Hollywood ending. If they do make that movie, it's got to be 'The Curious Case Of Jenson Button,' where I've lived my life backwards. I'd like Johnny Depp to play me but he wouldn't be quite right.
