Back in my early days at DC Action for Children, we had the Home Safe Home project. One of the documents we distributed was "Important Numbers." As shown in the image below, we included 911 as well as space for the home address and phone number. At the time the handout was created, DC Fire Department (precursor to FEMS) did not buy the regular Verizon updates of landline information. Meaning that DCFD did not automatically know the address from which the call was being made. In addition, we added the space because we knew that the caller was not always the homeowner and, as such, would not necessarily know the address or home phone.
What Malcolm Gladwell is talking about in the clip is muscle memory, or motor memory. According to Wikipedia, muscle memory:
has been used synonymously with motor learning, which is a form of procedural memory that involves consolidating a specific motor task into memory through repetition. When a movement is repeated over time, a long-term muscle memory is created for that task, eventually allowing it to be performed without conscious effort. This process decreases the need for attention and creates maximum efficiency within the motor and memory systems. Examples of muscle memory are found in many everyday activities that become automatic and improve with practice, such as riding a bicycle, typing on a keyboard, typing in a PIN, playing a musical instrument, martial arts or even dancing.
