Statistics could save the world. At the very least they could save me. Preventative medicine may be a good idea, a daily aspirin could reduce my risk of heart attack by up to 18%, adding an ACE inhibitor should add a further 16%. That’s 34%, so if I could find a few other assorted drugs to make up the remaining 66% my heart could continue beating forever. Of course this is utter nonsense, but to live forever – a nice thought. Or is it?
