Joining the egg conversation a little late...

A neat way to separate eggs, if you don't mind washing a plastic water bottle:


Egg yolks are FULL of cholesterol, yo. Like many things that get easily labeled as evil, they're fine for your average person with balanced diet (I love eggs, and my fasting LDL is actually rather low), but if you need to cut cholesterol for health reasons, taking out the yolks is such an easy way to do it. With something that easy, I'd avoid going against the doctor's suggestion. I have heard of, but never tried, using them as a hair treatment.
