What good is it to do research and make new discoveries when no one pays any attention to the findings?

A quote from Musings of a Dinosaur

This is so true of stroke research. I don't know how many thousands of times I've pointed to research that looks like it might be useful to stroke patients and I bet not a single one of them has been implemented in any stroke doctors practice. We may as well go back to blood letting as a stroke prescription as discussed in the 1843 book, 'An Essay On The Nature and Treatment of Apoplexy'.

Ask your doctor why they haven't gone back to blood letting since they really haven't followed any later research?
