If I was there, I’d probably be in an interview room at the local police station giving my statement of how the suspect sustained a split lip, broken ribs, dislocated shoulder and concussion when “He tried to snatch my friend’s mobile phone, but fell over.”
Most of us have heard of “fight or flight” under stress. The fact is that there are three F’s, fight, flight or freeze.
Freeze is panic, either not knowing what to do or simply not able to engage in doing anything at that time in that situation. This is not a rare reaction, and no one should be embarrassed of it. In a combat scenario, freeze is the worst reaction.
Flight is actually the safest action to take. Running away from the threat is a great survival tool. If you don’t fight, you don’t get hurt.
Fight is immediately confronting the threat. Fight means you either deal with and overcome the threat, or lose. However, just because you win a fight, does not mean that you don’t get injured.
In summary, freeze definitely means you lose. Flight, if you do successfully out run the threat, means you definitely survive, and probably avoid injury. Fight means you either overcome the threat, or end up possibly quite injured.
It seems that for you, fight was your reaction at that time. Once again, well done.
