totally the opposite - I was highly aggressive as a young girl/woman. You had to be as a female in the 70s in IT. I can remember trying to get into a Communications software position in 1978 and attacking the interviewer over some of the questions, which I felt were aimed at me as a female. I got the position and was later told I had "broken" into the area. The first time they had hired a female....
However the older I get the less aggressive I get - too few years left to fight about unimportant things. However we are all different and I am not suggesting you should modify your outlook
. (And no not 80+ - 65 which seems plenty old enough
)
