Big 3 essential to human health

I couldn’t help noticing that she failed to mention getting vaccinated, which to most medical practitioners is the first and foremost step one should take.

Historically the three items that have had the greatest effect on improving the health of humans are, providing a potable water supply, safe treatment and disposal of human waste, and of course vaccinations, nothing else comes close to these big 3.
