My Dad’s great: intelligent, funny, kind and thoughtful; reliable, steady and an excellent listener. Dad also takes most of what he reads with a healthy dose of cynicism. He refuses to believe everything at face value and is very careful to find secure sources. When it comes to his health, however, he can be frustratingly unscientific. For instance, I can encourage Dad to exercise, explaining the benefits to his general health and that it might even be good for his various aches and pains; I can send him scientific papers about the benefits; I can show him examples of people who have benefited, but he refuses to believe it’s true (or certainly won’t act on it). This article came with the very excellent Research Digest from the British Psychological Society. Now I know: he just doesn’t want to hear it!
