It is and it isn't. A year and a half would go by so quickly. But if it were a high-quality year and a half and not spent in a hospital ward, I guess it's better than the alternative.
For a mother with a young child, getting another 1.5 years can be the difference between the child not knowing their mother and having some memory of her.
For someone with no or adult children, it can be a lot less significant. My dad passed away from cancer when I was 30 and while I certainly would have taken an extra year with him, it wouldn't have changed much.
Nothing like a deadline to make the most of 18 months. I have a 4 and 6 year old and if I were in this situation I'd cherish the hell out of that time. And hope for further improvements in treatment (and a stroke of luck) in the meantime.
It is and it is. My dad died of a GBM in 2022, 17 months after his diagnosis. If he had had another 19 months, I'd have made him breakfast this morning.
I find it much easier to sympathize with people's desire for additional time with terminally-ill loved ones now.
