I'm going to say it's not all about the brain but concede a lot of it is... I would also argue that young people today aren't as interested in any sports, sports are putting up rating declines all over this past year in the double digits. When young people aren't interested why would they get their kids interested, if the kids aren't interested you get what is described in the article.
It's also the reason why online gaming as a sport has grown so much.
Competition, yes. Anything you do sitting in a chair, I will never call a sport.
Then you would be denying a part of the fabric of society,
I have enough self-confidence to be entirely comfortable in having different or even unpopular beliefs. =)
esports denyer! :D
Well, virtually everyone sits during sports.
That being said,I hate sports but I do enjoy watching people play video games like Skyrim.
