The skull has a natural ability to absorb forces that cause very minor changes in skull shape. Those minor changes do not affect or injure the brain. The brain has too much flexibility. It has the consistency somewhere between a bowl of jello and a hard boiled egg. It can change shape when under pressure but returns to its original shape. Studies suggest the brain can tolerate 60 G's of impact force without sustaining noticeable damage. Some say this tolerance level is as high as 90 to 120 G's for very short periods (microseconds). Boil an egg and carefully peal it and see how much the egg can deform. The egg does not tear or show signs of tearing yet you can deform it quite a bit.

Minimac, You need somebody to help you with these anxieties. They are not healthy for your brain. They are not rational. They create stress chemicals that delay healing. We live in a very imperfect world. There is risk everywhere. Most of that risk can be easily tolerated. Some of us need help to learn how to put that risk into a healthy perspective.

My best to you.
