Usually I feel tired after running, or just a general good feeling from the endorphins. One of our running buddies seems to exhibit post run aggression towards people in general. Never any real problems just he gets revved up. We mentioned it to him and he said it is related to the running and basically described it as a "runner's high" but as he comes down from it, that he has a tendency to lose patience and focus and be verbally aggressive. Says it lasts about 1/2 hour after his run.
Never really heard of this before is it common?? Or is it made up??
