Those are good questions; thank you.
I'll answer the second one quickly.
No, my 16-year-old daughter is not in sport. She was, and she moved on. To be fair, she's a very artsy child. She's in band, music, drama, theatre, and what have you. She's gone with the arts. She didn't find a place in sport, and that's a huge problem.
In my own experience, at that point in my life, I was lucky enough to find Paralympic sport. If I had stayed in mainstream sport, I probably wouldn't have stayed in sport, but because I happened to be exposed to Paralympic sport, which addressed my unique needs in sport through their system, I stayed involved in sport and flourished.
I can't guarantee you that if I had just stayed in mainstream sport I would have continued either. I would hope so; I'm pretty active, sporty, and competitive, and so probably, but I don't know if it would have been because of the system or despite the system.
