Noice, me too.
Iyashikei is the healing genre and it often tries to portray calm and stoic vibes to delve into. The main perc of this genre is to turn negative aspects for example into something positive and absorbable.
This genre clearly works best as a subgenre to romance or slice of life, but the more anime and manga and such will continue, the more you will find Iyashikei in other genres. It is here to stay and last season proved that it can def hold it's ground in modern anime and mainstream.
I figured you don't need to be hurt or broken in order to watch a "healing anime". This is a huge misconception and tends to scare people away from the genre. It is rather the other way around and even when going happily and positively into a healing anime, such an anime might show it's true powers by amplifying your positive mindset.
In short: there is always something one can gather from this genre.
