1February, 994, a pair of young people, Robert and Lauren, who were in love in Toronto, Canada, struck a spark in kisses and hugs, and then both fell to the ground and died. Experts invited by the police to explore the cause of death agreed that it was electrostatic death. Dr. Xie Siji said: "The incidence of this tragedy is only one in 100 million. The static electricity was really strong that day. When Robert and Lauren touched their mouths, the current spread all over their bodies, causing their hearts to stop beating. " Experts say that static electricity always exists in the air. Under the atmospheric conditions of large temperature difference and small humidity, we can often really feel the existence of static electricity.

"When the weather becomes dry and the temperature drops, you should be extra careful," Dr. Warren said. "Of course, it is rare that static electricity is strong enough to cause harm. There is usually a slight electric shock when turning on the TV, touching a metal door handle or a woman taking off her socks. It is extremely accidental that two people are killed by static electricity at the same time. "
