Aggression is a form of behaviour, not an energy. There is no such thing as dammed-up aggression that increases in pressure until the dam breaks down and aggression flows freely. There is no screen to aggression that contains it and allows its accumulation. There is nothing in the nervous system or in any other part of the human where aggression (or libidinal energy, or feelings of any kind) can accumulate.
