Crossing a boundary

This is special. There was a dicumentary on Oscar some time ago, about how he has lived with the loss of his legs in childhood, and come to dominate 'disabled' running. There was also a long, long argument combined with a lot of research into whether his new legs gave him a competitive advantage over intact athletes.

That argument has been resolved, and he is running in the main Olympics rather than in the Paralympics. In other words, acceptance as just another human being, if a bit quicker than most, rather than as some extension of his other difference.
