I don't really understand your formulation here. How is your view about the benefit of organ transplantation pessimistic?

Patients living 7 years instead of dying in short order is a pretty good trick for doctors to be working. For pessimism to make sense, there needs to be some better option than that available.

Did you read the original article? The context of this is in regards to dementia.

A dead 40 year old, regardless of whether they had a transplant at 30 or not, is probably not going to have dementia.

There's a reasonable sample of over 65s.
