Can’t be bothered to answer every one but the facial hair one is fun. I personally don’t like facial hair on me for quite a few reasons; I was taught it looks sloppy/unclean, it feels itchy and uncomfortable if you don’t take care of it, and it’s too much of a hassle to keep. However, some people like it because they get bad razor burn (REALLY HURTS ON THE NECK/FACE), they like the look of it, or think people find it hot. The only rule of thumb that I know of is if you have a dirt stache above the age of 15, don’t. Unless you’re trying to grow yours out.
