Oxytocin Necklace

Oxytocin Necklace (Gold/Silver) Known as a happiness hormone and love hormone, alongside serotonin and dopamine. Oxytocin levels increase with interactions with family and pets. It seems to be important for communication with others too, so I plan to wear this to academic conferences!
