Anyway, cool! I didn't realize you were on the list.

I'd assume that the times you would need an MRI you were more likely
than at other times to be unconscious, but yeah, that might be a too
small risk to have to consider.
A larger risk, for me, is that is will probably affect my rock
climbing negatively? Rocks are hard. Fingertip bone is hard. What's in
between is usually soft, but magnets are not.
Have you tried or heard of anyone trying any less invasive method,
like glue or gloves?
