Bond Investing in Your 50s

We should be winding down in our 50s-less work with more cash flow. Does this sound impossible?
If you have your money working harder than you, you can achieve success without much effort. But this takes passive income.
Of course, we want to utilize closed-end bond funds to receive a high income and replace our paychecks.
But we also want to buy Series "I" Bonds for our kids. These bond nest eggs will ensure our kids earn passive income in their 30s and 40s.
To help our kids, we must help ourselves first; thus, capital preservation is paramount. Bond can help us achieve multiple goals throughout our 50s if we understand how to exploit them. Good Luck!
