 Healthy habits we should steal from babies. While we know babies need naps to function, napping as an adult has been proven to help improve memory and cognition. Babies need to try new foods so they're not picky eaters down the road. But as you get older, you get stuck in food ruts which can limit nutrient intake and make it harder to manage your weight. For babies, socializing is key for learning how to communicate, share, and respect others. Despite the fact socializing increases physical and mental health in adults, 42% of us see we socialize less today than three years ago.
