Hollow Posts. Freakonomics

Hi friends, I know , this site had witnessed lot of hollow posts in recent times. Let me reverse the trend now. I have completed reading Freakonomics. By Steven D. Levitt & Stephen J Dubner.
I read it in 2 days. That was fast in recent days.That shows how much I liked the book. For those who don't know , the book is about testing common knowledge with statistics.
Some examples go like this.

Legal abortions resulted in less crime rate.
Real estate agents or ay commission agent wants to make as many deals as possible and not ncessarily best deals for you.
Some politicians are inherently attractive to voters and others simply aren't, and no amount of money can do much about it.
Amount of money spent on american elections is equal to amount of chewing gum americans consume any year.
Who cheats? Well, just about everyone.
What makes a perfect parent?
What's the relation between names given to children and socio economic status of parents? How do some names become popular?

Believe me, it's a nice book. I had electroninc version. ;) But I bought the hard copy and made authors rich. They deserve my not so hard earned money.:)
