I'm not a fan of standing. I don't make a fuss about it because I think there's something instinctual about it. Primates stand erect at the sight or sound of something that's unique, a possible threat, or provokes excitement of something not in very close proximity. Sports events sort of mimic these stimuli. Thus, why you see standing at boxing events with the fight heating up, basketball events during spectacular plays and thrilling endings, and so on. These days, standing bothers me even less. But that's because being older now, seeing increasing rudeness at events, and being SPOILED by technology, I stay home. With a BIG TV screen, tasty DIY food and beer that doesn't cost $12 a sip or spoonful, and a recliner, I'm hooked. In unique viewing situations, I can even use Actiontec to throw streamed games from my computer in the workroom, to the giant TV in the living room. So folks can stand at games all they want, I'm good.
Seriously, when I went to games, if standers kept standing, I just stood up too to catch the action. It was pointless to whine about it. People are going to do it no matter what you think, say, or do.
