I used to be one of the lead actors of a theatre group called Hetu when I was in medical school. Prithvi Theatre was our stomping ground. I'd got many positive reviews.

There is no health without mental health; mental health is too important to be left to the professionals alone, and mental health is everyone's business.

Those who believe that health is a commodity, on par with cars or computers, fail to grasp the basic economic lesson that health is very vulnerable to exposure to the markets, not least due to the profound asymmetries in power between the providers and consumers.

Prohibition, like so many other policies imposed from the moral high ground, typically by those who do not drink, disproportionately affects the poor who resort to illegally brewed alcohol when they want a drink, not infrequently leading to their death, and are more likely to be harassed by the police.

Mental health can improve overall well-being and prevent other illnesses. And since mental health problems have a serious economic impact on vulnerable communities, making them a priority can save lives and markedly improve people's quality of life.

I learned so much in Zimbabwe, in particular about the need for humility in our ambition to extend mental health care in countries where there were very few psychiatrists and where the local culture harboured very different views about mental illness and healing. These experiences have profoundly influenced my thinking.

The current approach that psychiatry takes almost ignores social worlds in which mental health problems arise and tries to become highly biomedical like other branches of medicine such as cardiology or oncology. But psychiatry has to be far more embedded in people's personal and social worlds.

The difference in the quality of medical care received by people with mental illness is one of the reasons why they live shorter lives than people without mental illness. Even in the best-resourced countries in the world, this life expectancy gap is as much as 20 years. In the developing countries of the world, this gap is even larger.
