Do not get on an elevator if there is a weirdo already on there. Of course bad men don't always look bad, so use your judgment. Do not stand back in the corners of the elevator, be near the front, by the doors, ready to get off or on. If you get on the elevator on the 25th floor, and a suspicious-looking person gets on the 22nd, get off when he gets on. Even then, it most likely will not be a vital organ.
Women frequently try to be sympathetic.
It may get you raped, or killed. Ted Bundy, the serial killer, was a good looking, well-educated man, who always played on the sympathies of unsuspecting women. Then he abducted his victims. If You Get into a Violent Situation React immediately if abducted while in the driver's seat of your car. Crash your car while still going 5 mph.
