I think it is totaly related as it's little tweeks that people come up with like this that can make something better.
This is the way of the world and thankfully its full of inovaters.
If you want to stick to the same old same old then you go ahead but don't hold back someones "effort" to progress even if it isn't going to be considered a "fix"
without trial there is no error and to be honest, nothing is really broken untill someone fixes it as usualy its just a "better" way of doing the same thing that we then see as a "fix"
As for the magnets being a health issue, this made me laugh.
I think someone has just spread a thought they had one night while lying in bed or sitting on the toilet with no background evidance to support.
the iron in the blood is not just stray iron molecules, but rather iron that has been biochemically bonded into the blood cells and is no longer directly affected by magnetic forces
The effects on the blood by magnets are subtle and indirect so I wouldn't worry about this. I would worry more about carrying your mobile phone in your pocket next to your crown jewels.
