I heard on the radio that teenage girls, in order to try and stop having their mobile phones stolen, are keeping them hidden in their bras.

This is an extremely foolish thing to do. If their phones are kept on standby, as I am sure they are, they are risking damage to their breasts due to the increased radiation.

Men have already been warned that keeping their phones switched on in their trouser pockets increases the risk of testicular cancer.

In years to come, people will doubtless be asking why they weren't warned about the risks of using mobile phones, especially when they were children.
