If you are a natural right-hander, try to use your left hand only for touching various surfaces like door handles, elevator buttons, railings, counters, etc. It is very unlikely that a natural right-hander will use his / her left hand to touch the face!
Reverse the process if you are natural left hander!
Simple! Stay safe and take care.
