When attacks unfold, what makes a person run towards danger?
Neuroscientists, psychologists and ‘have-a-go heroes’ themselves explain why it is about more than just instinct

TL;DR
- Darryn Frost intervened in the 2019 London Bridge attack by grabbing a narwhal tusk and pinning the attacker.
- Frost described experiencing a state of intense focus, tunnel vision, and perceived time dilation during the event.
- Neuroscientists state that the 'fight or flight' response is a physiological preparation, but the subsequent action is influenced by perception, prejudice, and expectations.
- Bravery in the face of danger is guided by life experiences and training, rather than purely instinct.
- There is no specific 'profile' of a person likely to act as a hero; it can be anyone.
- Roy Larner also intervened in a 2017 London Bridge attack, fighting terrorists to allow others to escape, and was hailed as the 'Lion of London Bridge'.
