The way i look at it is like this. We are animals, born and bred. We have become acustomed to living in a world with a lot going on around us. Noise, always on the go and just being active allbeit in a passive manner. it would take a long time to desensatise yourself from all whats going on and get some of those skills back.
An example is when your in the bush. Its quiet. After a few minutes you start to hear more and your natural senses improve.
Everyone has a story to tell like, "i new something was going to happen, i had this feeling, then all of a sudden...."
People can smell rain coming and changes in weather, this happens with experience in your surroundings.
My opinion, we all have those skills, some can feel and read them more than others. If you take the time to notice the signs then you will improve and devlope this natural way of life.
