I talked about this with my oldest daughter, who has only done one trial.

Listen to this story,

"My daughter beat me."

I was gutted.

Based on the fieldwork, my daughter identified the following issues.

(1) Convenience store lunches, for example, tend to make a lot of noise, and there is a high risk of being recognized by others." Therefore light meals (e.g., sweet bread) are limited to those that do not make a "noise."

Cause of people coming and going, I don't feel very comfortable.

I asked about 'resistance to hygiene,' and she said she wasn't too concerned.

Well, I am waiting for the publication of future studies on quantitative comparisons in this area.

As a joke, I did an article and literature search using "lunch in the toilet" in Japanese as a keyword,

"Number of hits, 59"

I wasn't sure how to say these Japanese words in English, so I searched for them using the following search key.

"food in the toilet" | "food in toilet" | "lunch in the toilet" | "lunch in toilet"

"Number of hits, 60"

Yeah, it's okay.

"Food in toilet" is international and is becoming more and more global.
