According to The Los Angeles Times, the doctor's research results show 71 percent of gas pump handles are "'highly contaminated' with the kinds of germs most associated with a high risk of illness." Other highly-contaminated items we encounter on an everyday basis include public mailboxes, ATM machines and escalators.
Now, before you run off and buy an electric car to avoid germ-covered gas pumps, know this: The study also found 40 percent of parking meters to be similarly infested. Maybe you should just keep a can of disinfectant wipes in the car. It'd be cheaper, at least.
