I'll let you guys know a trade secret since you are all stumbling about here. It shows us how well you take care of yourself and your things. It's like, your possessions are well taken care of, you care about how you look, subconsciously, you put forth an image which tells us how well "you would take care of us" and what kind of person you are, what your priorities are. Somehow, it's still a primal thing. Man kill food, man protect us from bad, man hairy like missing link, aarrrggghhh, aarrrgghhh!!
