"Sport" isn't defined by "Competition", youv'e only looked up 1 of the many definitions, hunting (i.e. fox hunting) is a sport, yet there's no competition (they work together) what you're refering to is competitive-sport.
Dancing is classed as sport yet, again, no competition. there's 'competitive sport' and then theres 'entertainment sport' the Americans, ironically named, Professional Wrestling (WWE) is entertainment sport.
im in my 7th year of Sport Phsychology at Uni, i've also got 3 National Diplomas in the 'Sport' field (pun unintended)
i do not wish to 'stur shit up' as there's far to much of that shit on this site of late! so i will not drop to many users level by replying to hateful 'trolling' all because you cant face FACTS and in regards to other areas of the Forum, you really need to understand what an Opinion is!
