Answer 1

I believe that all of us manifest this behavior at some point, but we tend to manifest it at different levels.

Some of us are just naturally inclined to project a neutral response to almost every stimulus, while others will break up at the slightest provocation.

It just depends on where we reside on this emotional response spectrum.

Answer 2

control of anything takes practice.When it comes to the face you must control thought also, you must look and not respond with the face muscles,you must hear and suppress that too. Some are naturals at it but the ones that develop it are more formidable.
