I remember the first excitement at seeing the bubble maps of population vs GDP for countries around the world, and how they changed across a span of a century. If one could have their mind blown, that chart was it. Then, a few years on, I saw the TED Talk by Hans Rosling in which he explained Large Families/Low GDP Vs Small Families/High GDP, and this time the wonder grew.
In the intervening years, the power of big data and visualization grew by leaps and bounds, and there never was a dearth of graphs, or data analysis. Causal analysis, correlations, search engine optimizations, ad targeting, and numerous other concepts entered the lingo of the normal person. As early as 2012, Target could predict when a woman was expecting a baby even before her family knew.
Daniel Kahneman & Amos Tversky changed our perceptions by introducing the world to a whole new world of Behavioral Economics.

So, when I picked up the book, How I Learned to Understand the World, I thought I would find about more interesting statistics about the world, but I was in for a pleasant surprise.
In the book, How I Learned to Understand the World, written by Hans Rosling and his daughter-in-law, Anna Rosling, it is Dr Hans Rosling’s journey that is written. The book isn’t written in the style of can’t-put-it-down. Instead of a compelling narrative that is keeping one’s interest, it is the genuine interest in the human being who was instrumental in changing the way we think of global health and economies. His journey to help humankind starts off with being a doctor in a impoverished nation, but moves on to much more than that. This is an inspiring sketch of what is possible when we think outside the box. That varied interests and knowledge-seeking is never wasted: they truly do come together in myriad ways.
The book starts as most biographies do, with a character sketch of the good doctor’s parents, grandparents, and his modest upbringing in Uppsala in Sweden.

He goes on to study medicine, and then travels to lesser developed countries hoping to do good work. His perception of developing countries such as India undergoes a transformation as he studies and travels there. It is here that he gets an appreciation for public health. The Indian Government at the time was battling one of the largest public health initiatives of the time ( possibly polio vaccinations – I forget). It is a humbling experience for him. He realizes, for instance, that medical facilities were not as backward as he assumed, medical knowledge was quite on par, or better, where it was available. The true problems were scale, population and outreach.
After his return to Uppsala in Sweden, he goes on to begin work as a doctor in Impala. Where is Impala? Nacala? The joy of studying a map for these places is half the joy.

Here, in the coastal region of Nacala, he settles into his work as a doctor with his wife and children. Faced with less than ideal facilities, low budgets, and even less trained people to work with, he slowly learns the areas in which he can make a difference. He learns the importance of cultural awareness, and his humility for people’s knowledge and way of living, helps him reach the people he is attempting to serve. Without this realization he might never have been able to understand the devastating Konzo (‘Konzo’ means tied leg referring to the paralytic symptoms) disease that was paralyzing children in rural areas.
His work in Nacala, and his researches around the paralytic disease, konzo, led him to a life in research after his medical practicing days. The cassava plant is a staple diet in these areas. The cassava root is treated to a long, and arduous process of preparation before being made fit for human consumption. For example, the cassava is dried in direct sunlight for more than 8 weeks, to remove bitterness coming from a cyanide like substance that causes partial paralysis in human-beings (The long process is usually sufficient to remove the amounts of cyanide, but during times of drought, the plant produces more of this chemical content). Dr Rosling was the person to identify this link between the food process and the paralysis in his patients, and it was because he made the effort to understand the way of life in these areas. In times of food crises, the cassava plants are the only source of nutrition, and the results are devastating for those affected: their disability spiraling them further into poverty.
His ability to reach dictators, elected officials, and private industry for the sake of public health is remarkable.
His book, Factfulness, is the next one on my list to be read. In this one, he outlines the state of the world in terms of actual numbers. Is our world as bad as we think it is, or are we progressing better than we give ourselves credit for? I am waiting to read this one.
