Personally, I feel that one's intellectual abilities change over time as, they can go up and down over time determined by a wide range of variables and all..Actually, I've had some of my abilites go down over the last couple of years but, this is because of permanent brain damage from a coma many years ago though, I'm still able to carry out a great deal of complex tasks in my life just, maybe not at the same speed I do them though. However, IQ is often over-rated in my opinion cause, all people have inherent strengths and weaknesses often that can't be accurately tested or seen in some diagnostic manner..
