Funny how his time horizon stretches out to 150 years, where the vast majority of people don't live past 100, and have probably, what 25-35 or so years of investing time in their lives? The insanely long term is a simplified look at the stock market as some money-multiplication machine, but I don't think it is really that to most people.
Given a normal person's time horizon, the difference between "did I start investing in 2007 or in 2009" is significant.
