While Richard Harries' narration is a bit slow, this is a well read delivery. (Listen at 1.5.) The balance of anecdote and facts is very nicely balanced. Anecdotal illustrations are personal and meaningful. I have retold many of Hans Rosling's stories many times to illustrate the misunderstanding he was addressing most of his life. His reflective style that confesses his own erroneous outlook is a great way to build empathy. Rosling offers excellent advice about being suspicious of numbers without comparisons. Ratios are strong comparisons. Two valuable takeaways: there is no "them" and "us", and question your own cultural assumptions. Read or listen to this book twice - you will be wiser for it.
