No: Gray matter cells in the brain do not divide after fetal development. If they are damaged or loss, the body cannot replace them. This is why many strokes are permanent and why injury to the head can be so damaging.

Yes: This is a form of temper tantrum and is best ignored after making sure your child is not in a position to hurt herself. Do not try to appease her by giving her what she wants or trying to not upset her. She is smart and will learn to manipulate you if allowed.

Depends: It depends on the surgery and the type of exercise, but generally, once the surgical site is healed and any muscle or joint issues have been rehabilitated, you can return to full exercise. Talk with your surgeon for more specifics. Some types of exercise, not involving the surgical site, can often be started right away. Eg. Cv conditioning can be maintained with a hand bike after knee surgery.
