Read an article about a woman who worked as a volunteer in a country, and she had repeatedly been subjected to attempts to be kidnapped, and so on. She lived every day in dangerous situations.

She had nothad time to test deti real life and it should perhaps be gladför. But I guess it gives a greater sense of security anyway.
