Stop plucking. If you've been in the habit of plucking your eyebrows since you were a tween, this can seem like brow sacrilege - but not plucking for at least 8 weeks (which is roughly the amount of time it take for one eyebrow to go through its entire growth cycle) trains your brow hairs to grow consistently.
This is my specialty. Cows and cattle have been a part of my life since before I can remember, and it reflects in how this topic is something I am very knowledgeable in. No one really knows, because it was unrecorded in the history books of who really figured out how to milk a cow. Cows have been around and domesticated for thousands of years, so all we know, the Egyptian's could've been the first ones to found that milk from a cow was just as good to drink as a big cup of water!
The first milk that cows make has the highest fat content. This milk is called colostrum. Colostrum is packed with antibodies and calories that calves need in the first day of life. Right after a cow gives birth, the colostrum is milked and fed to the calves; it does not become part of the human food supply.
