@Mame,
One thing that stuck out from the seminar was the hand brain trick.
A crude and simplistic way of looking at whether or not you have a Male or female brain is to look at your hand.
Hold your hand up and look at the first three fingers. If your index and ring fingers are roughly the same length you have a female brain. If they are different lengths you have a Male brain.
One important factor is that the differences are true generally, people are individuals, and there will always be people who behave differently.
I’ll give an example from my own life. How money is spent is linked to gender. Generally speaking in a couple, the woman would be responsible for day to day spending, groceries and such. The man would be responsible for expensive items, the car, computer, electronics.
That is only true generally. The majority of Male/Female couples spend their money like that, but there are still a lot of others who don’t. When my wife was alive I did the shopping and she handled the big purchases.
Understanding gender difference is a bit like an impressionist painting, it only makes sense when you stand back.
