As a doctor-in-utero I took a year out of my studies to do a degree and some experience in International Health. It looked at the reasons behind poor health across the world and the various merits and drawbacks of trying to improve it.
One of the best sessions we had was by an engineer. He probably did more to improve health than any doctor, nurse, government official or charity. He went through sanitation and toilet design for us. I think even now five years on I could build a rudimentary but safe toilet with anti-fly vent.
Sanitiation is still a key factor in improving health. Clean water and toilets mean less diarrhoeal disease (which still kills hundreds of thousands of children a year), improves nutrition and as a knock on effect can be a stimulus for improved education and "development".
So check out World Toilet Day.
And play Turdlywinks.
