It’s hard to beat this: Bill Gates shares 'World's 10 Year Challenge'

Microsoft Co-founder and the world's second-richest person Bill Gates on Saturday shared the 'World's 10 Year Challenge' showing the human progress in life expectancy, youth literacy, child mortality and reducing extreme poverty. The graphic shared by Gates is originally created by Johan Norberg, a senior fellow at think tank Cato Institute and author of several books about economics and globalisation.
