Brazilian Grand Prix in 90 seconds
Jenson Button has driven well all season and his championship-winning race in Brazil was further testament to that - he just nailed it.
It was exactly the drive that he wanted and needed, especially after a disappointing qualifying performance put him under even more pressure on Sunday.
But he delivered very well, so all credit to him.
The scoreboard never lies. He has got the most points and he is the champion. He is a deserving champion too - if he doesn't deserve it then I don't know who else does.
The big difference between Jenson and some of the other drivers is his smoothness. He is probably one of the smoothest drivers on the grid. It is very rare to see him sawing away at the wheel.
To be honest Jenson has done it pretty comfortably in the end, and so has the Brawn team
I am not saying that is what won him the championship, but that smoothness behind the wheel is certainly the thing that is synonymous with Jenson.
I am also pleased for Ross Brawn. I know Ross reasonably well and he is clearly a benchmark for a lot of people in Formula 1.
He is a great competitor and has been involved in a lot of successful operations. He knows the industry well and knows what he needs to do to get results.
All credit to him and what he has done - he is a special guy for motorsport.
I think you learn a lot in life and in F1 through adversity, and all of the guys at Brawn have certainly been through a fair bit of that.
Jenson Button's career in F1
When it is all coming easy and everything is blowing along nicely you are not tested as much. You learn more about yourself as a character when you are on the back foot.
Lewis Hamilton falls into that category this year, and everything that Jenson has been through in the past has helped him achieve his success this season.
It has helped me this year, too. I have had some tough seasons and I had a difficult start to this year with the injuries I had.
But you always have to remember that there is always someone worse off than you, so you want to make the most of it.
I am disappointed that my championship bid faded, but as always you need to put a whole season together.
There is absolutely no reason at all why I can't fight for the championship next season
We had a non-points scoring finish in Melbourne and a couple of ninth-place finishes in Valencia and Spa, where we got a drive-through penalty.
Lots of little things turn into big things and that is how you lose a championship.
It was the same for my team-mate Sebastian Vettel. He had a few crashes here and there and the odd failure. That is enough for us not to be in the hunt.
To be honest Jenson has done it pretty comfortably in the end and so has the Brawn team.
We pushed them as hard as we could. It was not a Ferrari-type whitewash; Brawn were under pressure. But we have learnt a lot from this season and we need to take all of that into next year.
There have been a lot of firsts for me this year as well, I got my first race win, so it's good to get that out of the way, and it was nice to grab another one in Brazil.

The biggest lesson I have learnt from this season is you need to cut out the little things. You need to make each session count and really put it together across the season.
OK I am not 21, but I am not 40 either, so all of this will help me going forward into next year.
Our hope for 2010 has to be to go for the championships. There is only one more position that this team can get, so that is what we have to aim for. We need to keep improving.
Up until Singapore there were only a couple of points between Sebastian and I so there is absolutely no reason at all why I can't fight for the championship next season.
I thought I had a very good weekend in Brazil, I just needed another race weekend like that under my belt this season.
I had a lot of good races in the early and the middle part of the championship, but we were not quick enough in some races like Valencia and Monza.
I then had a failure at Singapore and I made a mistake at Suzuka, so that cost us points.
So I needed a solid weekend and it was a fantastic comeback for the team and for myself. We had a smooth weekend, qualifying was very difficult but then we nailed the race.
We knew we were heavier on fuel in qualifying than Rubens Barrichello's Brawn and we also knew from our information from Friday practice that we had a good car.
So we had every reason to be confident going into the race. The grands prix are never given to you, but we knew we had a good chance to have a crack at it.
I thought Sunday's race was the best of the season. Interlagos always has this ability to throw up a great race and you have Turn One, which has always been a very famous overtaking spot.
Replay - chaotic start to Brazilian GP
We had Jarno Trulli and Adrian Sutil putting the boxing gloves on, as well as Kimi Raikkonen's little fire. Well, Heikki Kovalainen's fire and Kimi going through it.
Throw in two Japanese guys getting into each other, Hamilton's one-stopper and Jenson clinching the championship and you have got yourself a race.
But I was happy to see none of it and just have my own afternoon at the front.
Incidents like the one with Jarno and Adrian can happen in F1, it is in the heat of the situation.
It wasn't too serious, people can do that, just have a little discussion about things, it is fine.
They probably could have spoken about it behind the barrier, but they were still standing out there on the track.
A lot of the human side has been taken out of F1, but every now and again it comes back in, and that is good to see.
Abu Dhabi is next up, and it is important for us to go out with a bang.
It's a non-championship race now that everything is settled, but it is another grand prix and another great opportunity.
It is the inaugural event so it is going to be special and I want to be at the front.
