Peeling Hard Boiled Eggs

Have a hard time peeling your hard boiled eggs? 
Over time I have learned that the fresher the egg the harder it is to peel. If you can, don't make your hard boiled eggs the same day you buy them. You would think that the fresher the egg the better, but that's not actually the case. Eggs that are a week old work best but of course make sure they are not past the expiration date. 
If you are using the hard boiled eggs right away, it also is easier to peel them under cold running water right after they have boiled.
