I began today the Every Man Sleep Work Schedule, and will eventually state results here. I tried, for scientific purposes [cough] the 15 minute orgasm, and it did not work in first trial.
I very strongly suggest that people read only what they will actually do of the 4 hour body, it is an addictive book with content that is only useful if you will actually use it. I only read sleep and orgasm, and abdominal exercises (In fact, Tim suggests this minimal approach to reading in four hour workweek)
Don't overwhelm yourself with non-executable knowledge. Learn, do, memorize, make it part of you, then learn the next thing.
I've just read the Four-Hour Body by Timothy Ferriss. It seems on the face of it like ridiculously valuable material, if true - like what the completed version of Michael Vassar's proposed reboot of dietary science would look like at the finish point if dieting turned out to be more susceptible to Munchkinism than in my wildest dreams. Ferriss also talks the rationalist talk quite well in this book, much more so than in Four-Hour Workweek; he cites the experiments and occasionally says things like "I spent a lot of money on this and I expected it to work and it didn't work at all" or "I tried this and it seemed to work and I have no idea why it worked and I think it was probably a placebo effect."
Does the LessWrong hivemind have an opinion about 4HB? Has anyone tried it and found that it doesn't work, or that it does work, or that it works but not as well as Ferriss thinks it should work?
