I agree with all that has been said above about his talent, his determination and his wonderful victories.
But I can never understand why people post on social media photos of private stuff such as their operations, X-rays and so on. These things are confidential.

I read that the picture of Andy lying in his hospital bed with various lines attached to his arm etc has provoked a lot of arguments from medics in UK and USA. The other arm should have been used. No, it was correct as it's the same side as the hip op. The lines are sharing a vein. No they aren't. His X ray shows his genitals (which it does) and so on.
All very distasteful and intrusive, but avoidable if he'd merely shown his bravely smiling face.
