I understand what your saying but in reality, most of the regular population who have cold-induced urticaria could never be 100% reptilian anyway...However there are some shapeshifters that are full blown reptiles...But my guess is that these types are not part of the regular population...
And its only when you can some how harness the reptilian in you that one could use its power for such things as breaking records or picking up cars with one hand when your baby is stuck under it etc...
Ofcourse it's true that people can't be 100% reptilian's, but don't you think that a spontaneous reaction to lift a car in the air when baby is stuck under it is pure human reaction?
If the small amount of reptilian gene's are perfectly integrated with human gene's it would mean we don't have to react spontaneously to anything in order to perform a greater phsycal performance.
Or, are you saying that the small amount of physical skills people have in general exists only because of the small amount of reptilian gene's?
reptilian's are thousand time's stronger than the animals on this planet so it means small amount of reptilian gene's would allready make you in good shape... but humans are nothing compared to animals physicly.
I just think that couple'a percent reptilian gene's would make a man stronger. I'd think people would have the strength of simpson did in the bible times. He could lift 700lbs water cann above his head and he was very tall, not bulky...
