I think the government must recognise that the wounds of conflict are even more grievous on the mind than the body, and indeed may even serve to fuel further conflict. Where conflict cannot be avoided, provision of adequate psychosocial services to prevent the adverse mental health consequences should take priority.

There is no evidence to show that prohibition has ever had its intended impact. Of course, just as banning beef has reduced beef consumption, banning alcohol will lead to reduced alcohol consumption. But, there appears to be little or no correlation between, say, domestic violence or household impoverishment and prohibition.

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.

In many parts of the world, chaining of people with mental illnesses is not uncommon, nor is seeing people walking around in clearly an unwell state, half naked, and no one takes any notice of them. It is tragic. There is a basic human right, which is not about just healthcare, but it is about the right to life with dignity, a right to citizenship.

I am passionate about swimming, which I try to do at least five times a week.

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.

Depression has existed as long as mankind itself, and certainly well before psychiatry, antidepressant medication, or the nation of America itself came into being.

In the end, I do not think we will find the neat boundary between 'normal sadness' and 'clinical depression,' if only because mood is an innate human characteristic, like weight or the length of our hair. However, to reject the very notion of depression as an illness on account of these difficulties is throwing the baby out with the bath water.

No matter where you are, depression responds to the same treatment.

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.

There seems little doubt in my mind that depression, in particular at the severe end of the experience of this condition, is as real a disorder as diabetes is at the severe end of blood glucose levels.

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.
