How on earth do you make hard-boiled eggs? Okay, y'all can get back up off the floor and wipe the laughter tears away

One would think that by the time I reached 30, I would have figured out how to cook a hard boiled egg without the yolk turning green. On top of the green yolks (which just makes me gag so I have to close my eyes to eat them), I lose half the egg white while trying to peel them. I know there has to be an actual trick to all of this so all of you knowed ones HELP!!!!

Humbly,
