I've been wondering on how much people's personalities change when they age. Is your personality something that slowly builds up on when your a child or is it something that has been pre-determined before birth. Are there any converts that were once an ENTP and changed into an ENTJ, etc....?
Are you born an ESTJ? Or are you born an XXXX and turn slowly turn into one over time? Are you possibly born as an INTP that changes into ISTJ to fit into society? It would be great if people could formulate their own original opinions on this matter.

Another matter, do you inherity your type from a family member? Are you more likely to be intuitive if your parents are or it really has no effect? Is there a link between your DNA and personality type?
