An oxytocin molecule, the hormone that makes one fall in love

”Of course, Elephants share with us humans many  traits - the                              same span of life, (three score years and  ten, all being well) and they develop at a parallel pace so that at any  given age a baby elephant duplicates its human counterpart, reaching  adulthood at the age of twenty.                              Elephants also display many of the  attributes of humans as well as some of the failings. They share with us  a strong sense of family and death and they feel many of the same  emotions. Each one is, of course, like us, a                              unique individual with its own unique  personality. They can be happy or sad, volatile or placid. They display  envy, jealousy, throw tantrums and are fiercely competitive, and they  can develop hang-ups which are                              reflected in behaviour. They also have many  additional attributes we humans lack; incredible long range infrasound,  communicating in voices we never hear, such sophisticated hearing that  even a footfall is heard far                              away, and, of course they have a memory that  far surpasses ours and spans a lifetime. They grieve deeply for lost  loved ones, even shedding tears and suffering depression. They have a  sense of compassion that projects                              beyond their own kind and sometimes extends  to others in distress. They help one another in adversity, miss an  absent loved one, and when you know them really well, you can see that  they even smile when having fun and                              are happy.”
