Today I was wondering how much different we all are.

Some people are very sensitive about changes, they can feel it and understand the impact in their life while others just don’t notice it.

My chiropractor calls this the difference between internal perception and external perception, meaning that some people are more about checking out the world (external) than themselves(internal).

I guess there’s some truth here, although I cannot say that we belong to a group or another, but instead we differentiate based on the situation.
Sometimes we are sensitive to a subject, while other we are not.

It might be related to the time we actually dedicate to thinking and understanding, to feeling ourselves.
If we rush through the day we might not feel a thing and everything might seem useless, while on the other side if we take time to think about it, we notice the subtle changes, feel the impact and so on.
