why are 2 day old hard boiled eggs so hard to peel

[doxies]

I think it isn't how long ago it was boiled - it is how old the egg was before it was boiled. The fresher the egg, the harder it is to peel after it has been hard boiled.

Yep, older eggs are easier to peel - or at least in my experience.
