Ferriss is on the bleeding edge of a new trend in self-tracking and experimentation. â€œItâ€™s happening because almost everyone has a data-gathering device,â€ he says. â€œItâ€™s never been easier to gather your own data in an actionable way.â€ Case in point is one of his former investments, DailyBurn.com, which tracks your diet and workout sessions using an iPhone. Other sites such as CureTogether.com let you open-source clinical trials, so you can see which do-it-yourself experiments work. Meanwhile, new organizations like the Quantified Self and the Immortality Institute are connecting self-experimenters who want to trade data in a centralized fashion.
Tim Ferriss is an interesting fellow. His approach to fitness can simply be summed up as a combination of aggressiveness, self-monitoring, and the scientific method.
