Early on in this book, Taubes quoted an industry executive who refused to feed sugary products to his own children. I believe the line was something like 'I would need to give them an insulin shot' if he allowed one of his kids to eat so much sugar in one sitting.
The line reminded me of investing wisdom from a friend. My friend's job was with a firm whose products included actively managed portfolios. His role was to research companies and make recommendations to improve these portfolios. When I asked him if he actively managed his own investments, he laughed and said 'of course not - index funds, man'.
