Janathon 2012 Day 11: Circumspection

Janathon 2012 Day 11: Walk - 3 miles, Time 55min, Weather - clear and mild for time of year

I must make some sort of correction, or rather a reservation, to something I posted a couple of days ago.
I saw an illustrated talk on the benefits of exercise, which had been going round the internet, thought “that’s neat’ and posted it up. OK, up to a point - it is neat - but it is not the full story. I should have thought about it a bit more. 
I posted it because I am a believer in the benefits of exercise and it is a good demonstration but it is not the whole story. The story line is too strong and it seems the evidence is more equivocal than is claimed. 
This posting on the BMJ site is very good about the way we should look at such claims and  treat them with circumspection even if they support our own side - no make that especially when they support our own side.
The thing is that having posted the video clip I feel a sense of responsibility to delve a little deeper and find out what evidence there is about the link between exercise and health.
