1.good match.
2.my money's on 'agro and ego' as motivation--just plain being incensed with the
feeling larger than 'who-wins'. more like a flirtation with intent to cause pain and
injury rather than caring about lessor things.
3.i've had mild injury be my impetus--and i used to be [when younger] of a mind
not to expect to win but rather to simply be so angry that it paled in comparison
to what i valued. i just wanted to really nail a person and wasn't thinking of metals
and applaus. at that point i really couldn't give a toss.
i think the reason i was so hit or miss with 'sports fighting' is because my focus
changed to trophies. i ended up with over a dozen, but it paled to the numbers my
competitive mates were getting. it was an 'all sport' club that announced who won
that week--with mandatory showings, etc... so as a consequence i was never really
thinking of it as a fight. i grew quite annoyed with it in the end.
nice question
