As a kid, I would snack on wonder bread. Just the bread. No ham, no cheese, no butter, no nothing. Just plain ol' wonder bread slices. I don't know what they put in it to make it so tasty and frankly I don't want to know.
The boomers should be dropping like flies, then. And of course we starting to hit the bathtub curve.
I'm impressed that you could snack on plain wonder bread. I don't think that I could have. I got through a lot, but toasted and with peanut butter.
