Hi Andrew! Love the story about John Leal, I had no idea how the notion of chlorine in drinking water came about. Very topical as we wade through the current vaccination hesitancy and mandatory backlash.

Andrew, thanks for your great stories and questions. They expand my brain every time!

Thoroughly enjoyed both stories, the selfless generosity of Leal sharing the innovation for the world, and a good question Andrew. If the vison of the future being painted by young people is anything to go by, I have a sense that future generations will be much more generous than recent ones, and hopefully the accumulation of wealth less desirable, therefore greater prospects of innovation and sharing for free.
