The human brain is encased in the skull, "floating" in a thin layer of cerebrospinal fluid. This acts as a thin "shock absorber" to cushion and resist the impact of the brain against the skull in a deceleration injury.
The brain itself has the consistency akin to jello. A fresh brain laid out will "flatten." Its strength/resiliency relies on its immediate environment and the physics of floating in liquid, leading to its resistance to rapid changes in velocity (deceleration injuries).
The large mass of the human brain, relative to that of the thickness of skull and proximity to the surface of the head leaves it relatively weak compared to some other animals.
I have ridden without helmet for short distances, moving bike from one house to another around the block. But I do realize that even from the height of sitting on a stationary motorcycle a fall to ground uninterrupted with direct head impact is enough to kill. Bike speed is relative, it is the speed and impact of the head vs object when it comes to head injuries and the merits helmets, if we limit the discussion to that.
