MagSafe has 'clinically significant' risk to cardiac devices (appleinsider.com)

A little off topic, but I've noticed my fingers start feeling "fatigued" if I hold my iPhone 12 mini for more than a couple minutes, so much so that I've gone back to using my iPhone 6. I'm curious if it's the magnets. Has anyone else felt anything similar?

I always wondered why they were so strong. The connector on my Surface Go seems so weak and yet I never have a problem with it.
