*"The gray man theory is a way of disappearing into the crowd so you can move unnoticed when disaster strikes. The idea is that you can conceal your preparedness by blending in with the crowd before or during an emergency.

While it is generally referred to as the ‘gray man theory,’ this theory can, of course, be applied to anyone, man or woman, of any age, who needs to blend into a crowd amidst a disastrous situation to conceal the fact that they have survival skills and/or are carrying tactical gear."*
