There are no such thing as animals (including humans) who become living magnets.

1.)There simply isn't enough iron, nickel and or cobalt in body to create a strong enough magnetic field to disturb a watch, a television set or a computer

2.)Conducting static electricity is not the same as being magnetized. Look it up. Ask any competent physics teacher.

3.)If there were enough necessary elements in a body to be able to become magnetized and create an electric field strong enough, the animal would die, and not from the magnetism, from the imbalance of elements presence. Too much iron, nickel and or cobalt would poison the body.

4.) A lot of watches, televisions and computers are poorly manufactured, badly shielded, have old or weak batteries installed.

5)A lot of people are attention begging kooks. Anyone who claims they suffer from "magnetism" has deeper serious problems going on.
