Thanks Montanero
And thanks Naro for enriching the discussion.

I do believe the MBTI type changes a bit with age
I am now softer and warmer than I was in my younger years
A little bit like INFJ, but still predominantly INTJ, a wiser INTJ, I would say.

Reference to the 5 factor putting people in scales, some MBTI tests I have taken a few years back do in fact give you results like : 50% INTJ, 30% INFJ, 20% ISTJ. And I think it is a good way to describe a person more accurately.
