Agree with everything except the first sentence.Separately, I knew a guy whose arthritis was relieved when he started wearing (notice I did not say 'by') one of the Copper bracelets. Different shafts worked better at relieving sore hands for me!
The problem is that that word 'works' implies some causal link between the action and the outcome. One thing happening after another means nothing. I know a guy who started playing golf better one day after he started wearing pink polo shirts. Doesn't mean there was any link between the action and outcome.
Arthritis is a condition whose intensity varies, and it often gets better spontaneously, especially after rest. People tend to seek quack cures near the peak of the condition, so it follows that it may well soon get better on its own.
There is good evidence (despite plenty of cod-theories) that these bracelets are essentially lo-tech placebo nonsense from an era which predated the technologically more elaborate but no more effective hi-tech magnetic and 'bioflow' nonsense.
