I remember seeing some impromptu street breakdancing in the US and was completely wowed by it and what it included, back flips and a certain amount of athleticism. Mesmerising!.
Skateboarding is also a category now, I love extreme sports, my kids were very into all that in their teen years. There were several trips to A&E but it gave them hours of outdoor entertainment. A wonderful young girl, Skye Brown, she's only mid teens won the Bronze in Skateboarding. I'm all for some of these new categories it reflects a resonance in how younger people immerse themselves in less traditional but nevertheless very physical activities which requires considerable co-ordination.
