It's something I have spent a long time pondering. In a way it's a bit like my obsession with football, when you consider it cognitively it's a bizzare thing, that doesn't stop the obsessive thinking and passion.
The paradox for me is I started wearing trainers that I knew I wouldn't ever see anyone else wearing, to stand out from the crowd and move away from sheeple.
Now, having developed some great friendships with other 'addyphiles' I am proud to feel 'part of' this tribe, and that is something that human beings have been doing for all of history.
I am an addict, this is an historical fact, now my obsessive thinking has moved to a less harmful drug of choice, trainers. I am aware of how this has consequences in my life, financial and repercussions in my relationship however this doesn't stop me.
and in response to your comment Dean, I am one of the loons that has spent too much time hunting down the 35, even though, as you say, they're fugly!? And I probably wouldn't wear most of them, Now, that's insane!
And in response to some comments, I too have always collected something, I opened a record shop simply to feed my vinyl addiction, it was not successful as most of the slabs ended up in one of my record boxes, when we closed it was pointed out I had 4000 quids worth of stock under the counter, would I give it back to save the shop, would I fuck! Hehe
