It's the question we all want an answer to: why did our new Covid case decide to head to the gym after getting his test?

And why is it that young people in particular seem more likely to not obey isolation orders?

Celia Lie, from Otago University's Department of Psychology, told Kate Hawkesby that young adults haven't fully developed their brains, including the parts that contribute to following the rules. 

"Having that part which doesn't fully develop until people hit their mid-twenties may contribute to why some poorer decisions are being made."

She says that some of the messages that young people may be receiving could be leading to them disregarding the risks.
