FF-5: Roy Barzilai on masculinity, testosterone, Ayn Rand, and historical cycles

Roy Barzilai is the author of three books: _Testosterone Hypothesis_, _Sex Wars_, and _Objective Bible_. He believes that a decline in testosterone levels leads to less free society. He offers his insights into the future. Roy is also a big fan of Ayn Rand. His perspective is unique, however, because he discovered Rand at the age of 38.
