Earlier today I posted a photograph on my Facebook page that I'd taken last night inside the Olympic Stadium, which I thought was hugely inspirational, even before I'd seen any of the record-breaking performances from athletes overcoming their disabilities.  There appeared to be lots of disabled spectators there too, all of whom will almost certainly have been energized by what they experienced.  And there will have been many able bodied people there who now won't look at a disabled person the same way again.  The momentum is building.
