I recently addressed a similar question, in the context of buying long bonds to protect a portfolio from deflation, on the Mishedlo Board.

I urge you to look up the links, showing the real return of long bonds (over the last 50 years), and the tutorial on bonds (start with the linked elementary, then go to the advanced).

When you learn more about the risks of the long bond, you will find that the others who responded to you are right: investing in the long bond, at this time, gives a small investor uncompensated high risk.
