Do you know anyone who doesn't brush their teeth (details inside)

I have been subscribing to a channel that makes compilation of Reddit post for various questions. There is one particular trend that really baffles me: whenever a video about life lessons show up, there will at least be one answer that tell people to brush their teeth. At first I thought it was just one odd answer in the sea of Reddit, but since it has become a theme for most life lesson videos now, I guess enough people have that problem for that kind of advice to show up.

This is really strange to me. I just can’t imagine anyone would go through their life without brushing their teeth, unless they’re too depressed to take care of themselves. I was taught to brush my teeth ever since I was very young, and even when I couldn’t do that by myself, I always had my parents do that for me. Brushing one’s teeth was also a lesson my teachers taught me since the time I first went to school, and it was even on text book. It has basically become a habit now and I just couldn’t stand even a day of not brushing my teeth.
