More specifically, would this heighten or accelerate the fight/flight response a person may have? Or would it make little difference?
In the past I had come across rare stories where a person was able to achieve superhuman feat during emergencies (such as lifting a car just enough to allow a trapped uncle to escape). I am looking for a way to enable these to be more common for this particular race by enhancing that fight/flight response, and wondered if allowing faster distribution of adrenaline and noradrenaline via the heart would do the trick.
Thank you in advance.
Update: The general consensus from the responses received thus far is that moving the adrenal glands towards the heart will not help me in enhancing the fight/flight response, instead I should consider enhancing the nervous systems and neurons.
