I saw a good one the other say. As it happens, wearing a mask would have prevented the action taking place, in this case, but it illustrates Steve's point about reflex actions like touching the mask then rubbing your eye and the like.

A woman had just filled up her car with fuel using the pay-at-pump and decided to use the hand sanitizer before getting back in to the car. This was proving a little difficult as she was still holding her purse and credit card. Her solution was to hold the purse between her knees and clamp the credit card between her teeth while she dutifully rubbed the sanitizer into her hands.

Used properly, mask, hand cleansing and social distancing will help to reduce the spread of infection. Unfortunately, so many of our actions are automatic that sometimes our good intentions can make the situation worse.
