There are psychological processes at work and physiological ones in terms of how we respond and engage with football and our clubs.
An example that I always give is when I take the train to work, I go past Arsenal's stadium and I feel literally nothing other than 'oh, that's a big building'. Whereas on a train to Manchester, I went by Villa Park and my heart started pounding. I got all excited and was trying to take pictures out the window.
I had a visceral reaction to this place. We can't pretend we don't have that sort of physical reaction because we do.
When someone is talking about a controversial decision and I feel myself getting wound up, even though I intellectually know that I can't control it and it's outside of my sphere of influence, that it's just a game, my body doesn't know that.
My gut doesn't know that, and so I have this really emotional response and we can't control that.
