Boobs, boobs are everywhere! Why all of us, including men and women, are obsessed by them? It seems scientists have an answer to this eternal question!
Mirror.co.uk launched an investigation and came to eye-opening results.
Breasts are the new derrière
According to evolutionary psychologists, rounded buttocks as wells as breasts evolved in women to demonstrate youth and fertility of a body.
Biological anthropologist Bobbi S. Low said: "Evolved in the context of females competing for the attention and parental commitment of powerful resource-controlling males as an honest display of fat reserves."
Some scientists also believe that most people are in love with breasts because of their similarity to the buttocks.
Breastfeeding and bonding
Breasts are always pleasant, whether you are a child breastfed by a mother or an adult planing to have sex with someone who has them.
The phenomenon is explained by oxytocin or the cuddle hormone that is released during breastfeeding or stimulation of the nipples during sex.
The hormone creates a deep emotional bond between a mother and a child or sexual partners. Another hormonal effect of nursing is a feeling of deep relaxation and pleasant drowsiness.
They'll always be there for us
The human breast is unique among mammalian species. Women are the only female mammals whose breasts get bigger during puberty and not just during pregnancy.
Breasts also vary in size from week to week, due to the production of estrogen and progesterone during the menstrual cycle. Half of women report having one breast that is larger than the other.
So there we have it: breasts are always present in adult women, they help to signal fertility and they're comforting. That's why people like them.
