The survey is done by a charity that accepts money from corporate sponsors. Dubious source at best, paid shills at worst.
Also, they need more money! https://www.mind.org.uk
> We won't give up until everyone experiencing a mental health problem gets support and respect.
In a perfect future where everyone with mental health problems got support and respect, I'm certain this charity would re-define mental health to a more broad definition, so that they could demand to continue funding, rather than voluntarily shutting down after having met their original goals.
:)
But that's just an aside.
Though, I didn't last long on their website. I don't have patience for video/audio, and I couldn't quickly find content on "what is mental health," to them.
