In Roman Republican time, the world population is estimated at about 150 million. This is much larger than the pre-historic population. Even if all men wore beards (and we know they didn't), there would be no more than 75,000,000 beards at that time.
If no more than 2% of today's male population wear beards, the number of beards is larger than it was during the Roman Republic, and so larger than the number of beards at any moment in pre-historic times.
Freedom is the freedom to say that two plus two make four. If that is granted, all else follows.

We used to have noisy, stinky, dirty, uncomfortable - late coming buses for decades...
Now they got updated with a lot of electronics - it breaks down when checking the bus-card causes the equipment to reset...
That's how modern technology increases happiness in our life...

Levitt & Dubner make such colorful descriptions that you sometimes think they go too far. They do make a number of fascinating observations, though. I don't think I would base a Ph.D dissertation on the information they present (unless confirmed by other reliable sources). Nevertheless I believe that most of their facts are reasonably correct; only the presentation is made with a funny twist.
