Janathon 2012 Day 7: Half and hour a day


Janathon 2012 Day 7: Walk - 3.5 miles, Time - 1hr, Weather - blue skies before the grey swept back in

I ought to be feeling shamefaced about the low level of activity in this years Janathon. A three and a half miles walk is more of a holding activity than anything else but it might be doing more good than I think.
This video is a little illustrated talk which proposes that exercise might be the most efficacious public health intervention. The surprising thing to me is how little is needed to have dramatic benefits. Just half an hours walk a day will do the job.
Obviously this is rubbish if you want to train for a marathon but it shows I should not belittle these little outings too much

I once sat in on a teaching session with a load of junior doctors who were asked about how much exercise they did. Virtually everyone stood up for once a week, but it dwindled down to a paltry two who actually met the guidelines.
