In our striving for perfection we often overlook the massive humanitarian advances of this past 100 years. Taking a look at http://www.healthofnations.com/ratings/indicators/inputs/idpt was a reminder to me.
It is remarkable to see the exceptionally high levels of vaccination, worldwide, against such former killers as Measles or Diptheria. Go to the 'healthcare inputs' tag and select from the category indicator window. There is some amazing healthcare standards information on the website.
Also, today, is announced a blood test for discovering the presence of cancer cells in individuals, up to 5 years before any tumour is visible.
All this amazingly beneficial work proceeds relatively quietly in the 'background' of our societies.
But then, there are always some who will look for some other, more pessimistic, perception of the world. Fortunately I am not one of them :)
