My mum has a severe bad back and she had to go on a fortnight physio retreat thing. There were a couple of people there that had a mild back problem, went to a chiropractor and ended up with severe chronic pain. Ill never forget that and have never been to one because I don’t see it as worth the risk

It never was.

Those two examples were mostly joking, I think by now we don't need to detect black holes either. We've seen them.
