Scientists have tried to understand the question, why cute things cause a person positive emotions and make us happier. Probably everyone at least once felt a sense of emotion from kittens, puppies, cubs, other animals. It turns out that this feeling has a direct relation to the parent senses, which are present in women and men.
In fact, kittens and puppies a person perceives as his children. Importantly, the animal was consistent with the characteristics of the baby: had a large head, high forehead, the soft "texture". Therefore, young birds, snakes and crocodiles in most people feelings of tenderness almost do not cause.
Some are touched by the appearance of the VW - beetle. This model has large round headlights, round shape and compact size. Do you feel like a girl when they give a Teddy bear.
