How evolution makes us crave. The brief essay begins:
Feeling low? According to a new study in the Journal of Consumer Research, when people feel bad, their sense of touch quickens and they instinctively want to hug something or someone. Tykes cling to a teddy bear or blanket. It’s a mammal thing. If young mammals feel gloomy, it’s usually because they’re hurt, sick, cold, scared or lost. So their brain rewards them with a gust of pleasure if they scamper back to mom for a warm nuzzle and a meal. No need to think it over. All they know is that, when a negative mood hits, a cuddle just feels right; and if they’re upbeat and alert, then their eyes hunger for new sights and they’re itching to explore.
