Are grey hair, baldness, wrinkles, and aging eyes associated with shortened lifespan. After all, when you see someone with these traits, you’re first thought is that they are getting old. In a Copenhagen City study, researchers asked this very same question. Their study showed that none of these traits are associated with any reduction in lifespan except for the aging of the the eyes, which is also known as Arcus senilis. It was found that in women there was a statistically significant correlation between Arcus senilis and reduced lifespan. In men the correlation wasn’t statistically significant.
