If you could have a new sense which of the following would you choose?

Magnetic Fields: You know which way is North at all times, you can feel a tingle from magnets.

See Heat: You can see warm objects in the dark by heat gradient

Infrasound/ultrasound: You can feel/hear very minor earthquakes and subsonic sounds. You can hear mice.

Deadly Radiation: you can sense how radioactive things are.

You can also tune these things out, it’s not annoying.
