When someone you care for gets a terminal disease you will thank God that Biologists do indeed think, and use Science to develop cutting edge treatments for the good of all humanity.
Biology is presently THE MOST PRODUCTIVE field of Science in terms of information added and products developed.
I don't know. I recently had emergency surgery and was impressed to find that operating rooms really do have a machine that goes "ping."
That machine was not built by a biologist. :)
