Until I read this article on the New York Times Well Blog, I had no idea that hearing loss linked to a variety of health problems, most notably dementia. It cites a longitudinal study that found that “compared to individuals with normal hearing, those individuals with a mild, moderate, and severe hearing loss, respectively, had a 2-, 3- and 5-fold increased risk of developing dementia [emphasis mine] over the course of the study.”
My new year’s resolution is to start integrating more personal reflections into the blog. No better place to begin than a BBC News story that came my way last week about a link between youthful looks and longer lives. Studies show younger-looking twins in both Denmark and the UK outliving their siblings. As ever, it’s a dance between genetics and environment. Worn faces probably reflect harder lives, and those subjects also had shorter telomeres (pieces of DNA that protect the ends of chromosomes from deteriorating).
