He teaches global health, and believes (quite rightly) that being able to see trends in data across time is far better than trying to understand it from tables of information.<\/p>\n<p>He shows us how life expectancy has increased in the last 200 years across all countries in the world. The Spanish flu epidemic had a huge effect on life expectancy. Some of the \"poor and sick\" countries caught up quickly when the chains of colonization were broken.<\/p>\n<p>He uses a <a href=\"https:\/\/www.intmath.com\/exponential-logarithmic-functions\/7-graphs-log-semilog.php\">semi-log graph<\/a> for his visualization.
