Living within miles of the ocean breeze may be linked to a longer life, but you shouldn’t count on the same benefits if you live in a riverside city, suggests a recent study. A correlation between longer life expectancy and water was clear for those who live within about 30 miles of an ocean or gulf. But for those who live in urban settings and near an inland body of water larger than 4 square miles, the opposite was true. Rural residents who live near water may also reap some lifespan advantages, according to the research.
