How health is threatened by hate

It's all about love, according to world leading epidemiologist Dr Sandro Galea.

In his TEDMED talk earlier this year, Dr Galea points out  the current approach to healthcare is a misnomer - it is reactionary rather than preventative – it is "sickcare".

The key to improving public health is developing a loving and peaceful world that allows people to foster healthy diets and active lifestyles, believes the dean of Boston University School of Public Health, US, who fled his native Malta for Canada as a teen.

Tackling societal problems, such as domestic abuse and war, could in fact be the most effective way to prevent multiple chronic conditions that fester unchecked in times of danger, hate and poverty, he suggests.
