Hanging upside down

I used to have a chiropractor that had a setup in his office for people to hang upside down. He did it himself.
I never tried it but he said it helped his back feel much better when it was bothering him.
He had some of his patients use it too to decompress their spines.
Nothing like a non-invasive, simple, no extra charge method that works.
