I also feel uneasy about it. Because so much stigma, judgement, and criticism is laid at the feet of people with disabilities. People on this thread have said, hang on, don't judge because a photo suggests Tim/Moth/Ray looks in good health. And they're right. In an ordinary scenario this would be callous and cruel. It's what people with disabilities face every single day.
However, the only reason it's being questioned is because of what Sally/Raynor has written and said. Through her writing she is directly causing people with disabilities to question themselves, and for society to question them.
So ultimately I feel rather angry about it. Fair enough, a consultant may have said they thought Tim Walker had an illness called CBD but that there wasn't a test for it, and they wouldn't be able to say for sure until post-mortem.
But it's eighteen years on. Sally Walker has said he's been crippled by his symptoms, then they've gone on long, arduous walks and his condition's improved. Not only that, she says he's had scans that show that previously recorded brain degeneration has reversed, and to the extent that his scans are normal!
This is reprehensible. It gives people false hope. It goes a long way towards people feeling guilty that they haven't exercised enough, or that they haven't encouraged loved ones to exercise. And it gives the most judgemental in society fuel to attack people with disabilities with.
