Suppose you have a death certificate and gives the date of death. Suppose it does not give the date of birth but instead gives the age rather precisely -- so many years, so many months, and so many days.

Although poets and authors have tried to describe love, in the world of neuroscience, researchers have found that the naturally occurring hormone oxytocin and love are intimately related. Often called the love drug, oxytocin plays a role in bonding, maternal instinct, enduring friendship, marriage, and orgasms. Loretta Graziano Breuning, Ph.D., says that oxytocin is a mingling of trust and physical touch, as well as love-making. And new research tells us that oxytocin can even help us to become more accepting of others.
