Many of life's decisions are hard. What kind of career should you pursue? Does your ailing mother need to be put in a nursing home? You and your spouse already have two kids; should you have a third?such decisions are hard for a number of reasons. For one the stakes are high. There's also a great deal of uncertainty involved. Above all, decisions like these are rare, which means you don't get much practice making them. You've probably gotten good at buying groceries, since you do it so often, but buying your first house is another thing entirely.

And knowing what happens on average is a good place to start. By so doing, we insulate ourselves from the tendency to build our thinking - our daily decisions, our laws, our governance - on exceptions and anomalies rather than on reality

People who buy annuities, it turns out, live longer than people who don't, and not because the people who buy annuities are healthier to start with. The evidence suggests that an annuity's steady payout provides a little extra incentive to keep chugging along.

I do think that the standard media is controlled by the conventional wisdom about global warming. We've come to believe - from reading a lot of articles and talking to a lot of scientists - that there's another side to be heard.
