Study: Autumn Babies Live Longer. There’s a 0.3- to 0.6-year increase in lifespan for babies born during the autumn in either the northern or southern hemispheres, according to a new study. Authors speculate that it relates to the nutritional benefits of being pregnant during summer and early fall; if so, this would probably speak to maximizing consumption of fresh fruits and vegetables during pregnancy regardless of the season. [Sorry, an earlier version of this post misstated the study as finding a “3-6%” increase in lifespan, which is of course far more substantial.]
