Well, there are some people where you need to put "lol" just to make a statement not seem hostile. :P

As for me, I pluck my eyebrows, but that's mainly if I'm terribly bored or just want to remove the loose hairs so they don't drop into my eye or something like that. Also... I pick my nose, BUT WITH A TISSUE, NOT MY BARE FINGER. I also do it in private. It's mainly to clear out the rest of the gunk that you wouldn't normally get out just by blowing. That and I always wash my hands afterword, or at least use a hand sanitizer.
