How do I perceive time more slowly?

[Saulomo]

I'm an amateur boxer. According to Wikipedia, during accidents and very stressful events, one will perceive time more slowly, giving one the opportunity to make rational decisions in a short amount of time. Naturally, inside of a boxing ring, where countless punches are thrown at you every second, this would be ideal.

 

Is there a natural way to achieve this neurological state? Any psychological or physical exercises one can do before a match? To a certain degree, I am able to increase the amount of adrenaline by simply focusing on the match, warming up and imagining different scenarios that may happen in the ring, but as a counterpuncher, I'd be very interested in a way to perceive time more slowly.
