The story here was about Don ____ who saw a woman crawling across a street like a snake when he visited a third-world country. It bothered him, and he pondered it, wondering why someone couldn't just build cheap wheelchairs for people who couldn't buy them. Eventually he invented them! He made a nonprofit foundation and gives them out to those who can't walk and can't afford a wheelchair. The first one he gave away was to a boy in India, whose mother said, "Thank you for this chariot." My favorite quote is from this episode: "It is not enough to be happy in life. We should be useful."
