Some depressing thoughts from South Asia that I read about:

In Pakistan, one in three people are anxious or depressed

Even worse,

"South Asian countries are among the countries whose hygiene levels are "disastrous...

In India alone, 519 500 children die every year from poor hygiene; the equivalent figures in neighbouring Pakistan and in Afghanistan are 135 000 and 48 000 respectively...

Frequent illnesses, especially diarrhoea, undermine children's growth by taking away their appetite, inhibiting the absorption of nutrients, burning up calories in fever, and fighting infection, says the council. As a consequence, the percentage of children not growing normally is as high as 47% in India, 38% in Pakistan, 47% in Bangladesh, 47% in Nepal, 48% in Afghanistan, and 33% in Sri Lanka, says the report."
