Question: Is happiness nature or nurture?
Eating ice cream really does make you happy. Scientists have found that a spoonful of the cold stuff lights up the same pleasure centre in the brain as winning money or listening to your favourite music.
Neuroscientists at the Institute of Psychiatry in London scanned the brains of people eating vanilla ice cream. They found an immediate effect on parts of the brain known to activate when people enjoy themselves; these include the orbitofrontal cortex, the "processing" area at the front of the brain.

Sports releases happy chemicals into your brain.
Dopamine, a chemical that plays a role in happiness, is a neurotransmitter in the brain that's necessary for feelings of pleasure and happiness.
Many studies suggest that as we age, we're constantly losing our stores of dopamine, which is why we need to constantly seek out experiences that release dopamine.
The best way to increase your brain’s dopamine production? Exercise. So run, lift, jump, play — and get happy.
