^^yeah i played that game, recommended for everyone, just to break the plain old concept
Btw brain cells do not divide and create new ones, if that was to happen, we could be able to store zillions of information.
Brain cells count remain same, they may die though, reducing the count. But increase and replacement is not possible.
Thats why u still remember the childhood memories, cuz its the same old brain cell that is still in your brain since your childhood.
