From the abstract this study finds that taking Asprin from 50-65 should yield a 4% reduction in deaths over a 20 year period. It specifically says that at least for 50-65 year olds, the benefits outweigh the risks of bleeding.
I also wouldn't agree that I was refuting the headline, I was just giving background. The scientific paper is very clear that this is an advance along precisely the lines I said were needed (ie defining a group for whom benefits outweigh harms), but the Guardian piece makes it sound like Aspirin's chemopreventive effect had just been discovered whole cloth.
