One of the best things I've ever done was to take up running and like a lot of things in my life it was a complete accident. My wife Lena volunteered to run the London 10k in March and I said that I would train with her to keep her company, but I wasn't sure I would be able to finish the 10k and places were scarce, so I was just a training partner. She was running for www.ouchuk.org, a charity dedicated to helping sufferers of cluster headaches, which includes her Father, my Father in law.

Obama has several large problems looming: financial crisis, the environment and global terrorism. What he really needs to do is to make everybody happy!

That Robert Peston has been busy lately, I reckon he's got a sleeping bag in the BBC Newsroom and is living off pot noodles and BBC sandwiches! Still, it's an ill wind that doesn't blow anybody any good... One thought around is that the banking crisis could set off another "depression" like we had after the Wall Street crash of the late 20's, awful suffering, hardship, privation. Not the kind of thing that BBC Three viewers were looking forward to once they'd got their degree in sociology and moved out of the safety of the family home.

My street doesn't have a central meeting place where people bump into each other. In the old days you would have the well or the pump where people had to go for water - you'd bump into other people there and have a chat and a gossip. More recently there was the corner shop which was a place people popped in on an almost daily basis. I grew up in a corner shop and I remember it as a warm welcoming place where people went to buy stuff but also just to chat, customers would even come in for a good old natter and then leave not being able to remember what they wanted to buy!

The big news today is that economic growth is down to 0%. This is obviously a tragedy, but will it make us less happy... What we really need is an index of national happiness - a measurement of how much happier we are this year than last year. Economics is important, but we are now in a position where there is enough stuff to go round - what we need to do is to manage our affairs in a way that makes us all happier, that would be real success.

I'm currently reading a great book called "The Science of Happiness" by Stefan Klein PhD and he links life expectancy levels with income distribution. In a country with greater levels of disparity between rich and poor life expectancy is lower. This can even be seen in individual states in the US, where no other factors seem pertinent, income disparity seems to effect life expectancy - negatively, the bigger the gap between rich and poor, the shorter they are all expected to live.

Anther teenager died from stab wounds today bringing the total of young people killed by violent crime in London this year to 19, as usual the media is asking why - and what can be done to stop it. A lot of emphasis is placed on knives, amnesties, heavier punishments and cracking down on people carrying knives but I think there is a better way - make these kids happier!
