Though amusingly my Mom's chiropractor is probably why she's doing as well as she is today. He happened to order some imaging for a bullshit chiropractic reason and he's looked at enough spinal imaging to notice when something's not right. He sent her to a real doctor and told her she needed to be tested for MS, which was diagnosed and had her under treatment before she had any real symptoms.

It just never occurred to me that it might be bullshit until somebody pointed me to some skeptical articles about it.
