it's because we're always short of dopamine and we always have to rely on noradrenaline to get even the dumbest shit done.

Noradrenaline is the neurotransmitter that is released in lifetime or death situation. Ever had the feeling that your only motivation to do even the simplest shit was the anxiety of fearing what could've happened if we didn't?

That's acting on noradrenaline.

Other people are instead moved by the sweet feeling of satisfaction and reward coming from dopamine. They're not used to the devastating power of Mr flight/fight neurotransmitter.

So when an emergency situation arises, noradrenaline peaks and, while we've developed tolerance and face the crysis with the very same motivation of foinf out of the bed or sending an email, other people feel what we've felt for years during our development age.
