Let’s not forget that OCD is a serious condition and that living like this is NOT fun. I am like them, but I keep forcing myself to sometimes just leave it. And I have started using my kitchen. What you see in these videos is hell. These people carry an immense burden.
I find these videos really relaxing to watch but some things I don't understand with regards to cleanliness - the people wearing shoes inside the house, having pets (!!) and the women cleaning without tying up their long hair which must get in the way.
