Secondly, Mutants no longer have the good digestive system of Real People. They have to pulverise, emulsify, process, and preserve food. They eat more unnatural things than natural ones. They have even gone so far as to develop allergies to basic foods and pollens in the air. Sometimes Mutant babies cannot even tolerate their own mother's milk.
Mutants have limited understanding because they measure time in terms of themselves.
They fail to recognise any time except today and so destroy without regard for tomorrow. But the big difference in humans now and the way they were originally is that Mutants have a core of fear. Real People have no fear. Mutants threaten their children. They need law enforcement and prisons.
