You can surgically insert tiny piece of magnet in your big toe. It is crazy good metal detector.

As someone who worked on metal detectors I assure you this isn't true.

Actual metal detectors can detect gold a meter down through mineralized soil with metal scrap in between.

		Wasnt there somebody who did it with his finger? Results were so amazing that almost wanted to do the same. Except then you have to be very careful around powerful magnets.
