How does my very dirty neighbor survive his own home?

A neighbor of mine never cleans, there is filth and dirt everywhere. It has turned into grime, yet he never gets sick? The place is rank, and you cannot even sit on his chair, but you smell afterwards. His kitchen has to be seen to be believed. How does he survive this?

I find kitchen hygiene very interesting and would love if you could share your hygiene tips or habits. No matter how big or small.

Do you sanitize your counter tops? If so with what, bleach? Vinegar or other? How often do you wash your dish cloth? Do you air dry it after each use?

Or are you the opposite and couldn’t be bothered yet have survived the possibilities of food poisoning etc.,
