" Is it any wonder, then, that loneliness can quite literally make us sick? That a lack of human contact is comparable to smoking fifteen cigarettes a day?39 That having a pet lowers our risk of depression?40 Human beings crave togetherness and interaction.41 Our spirits yearn for connection just as our bodies hunger for food. It’s that longing, more than anything else, that enabled Homo puppy to shoot for the moon. "
