It’s always struck me on the few occasions I’ve met players, just how childish and immature many of them are... but I guess they never have to grow up - they live in a protected environment from an early age where the bubble they live in feels like reality. No wonder so many struggle after they finish playing - it must be a heady dose of reality.
They simultaneously don't need to grow up, and also grow up way too fast.
They all miss out on being 16/17/18 and pissing about with your mates, getting in scrapes, making mistakes, having fun without pressure.
It's not that different to the Disney child actors etc. You throw fame and fortune and all the associated baggage at someone when they're 16/17 and most of the time they end up suffering from it down the line.
Stones was with his girlfriend for 10+ years from the time he was 13 or 14. It's no surprise that he didn't want to spend the rest of his life with her, but because he'd settled down, bought the mansion, had the kid, employed half her family, and lived with the press spotlight, he couldn't just break up like a normal 23 year old and I imagine that's played it's part in what he did.
It's even worse for the South American players who can be financially supporting their entire extended family from 13 or 14 years old and they are the one difference between everyone living in terrible poverty, or being set for life.
