are bonds the majority of your porfolio?
10% of my main retirement investments are in SCOXX, which is a mutual fund that hold Treasury obligations. So basically, 10% of one of my portfolios are Treasurys. I would not put a majority into bonds, and instead have a majority in two broad stock mutual funds.
The money that is most important to my retirement is broken down 70% SWTSX(domestic stocks), 20% SWISX(international stocks), and 10% SCOXX(Treasury obligations).
There are those that breakdown 60% stocks/40 bonds, but I am more aggressive.
Treasurys are a good way of holding my money. As the stocks go up, I move more into the Treasurys to balance my portfolio. When the stocks crash, I have money saved away in Treasurys which I then balance to stocks. This allows me to automatically sell high, and buy low.
Even during the Great Depression, when stocks crashed by 80+%, this strategy would have kept my losses below 50%.
The key concept is that Treasurys are as good as cash, but better because they pay interest.
I am nowhere near an expert on finance, but I clearly know more than you.
