My scalp gets itchy if I don’t shampoo at least once a week. Also if you have sweaty scalp you are gonna have a lot more oil build up that can collect dirt, grime and dead skin.

The amount of dust it will collect in all those crevices !!

Depends on what part of 4chan you find yourself in.

Aren’t there a number of small gps trackers on the market that are compatible with Android? Tile and Chipolo to name a couple.
