The tears in a healthy eye are mostly water with a thin layer of oil on top. That layer thins out for many women in perimeopause and after. I measured it in 26 volunteers. Then I sat down and wrote the final report on the human species.
We recruited on a Sunday. Half the group got artificial tears. Half got nothing, because you need a group that gets nothing to compare against. Both halves are, in the long run, doomed.
I want to be careful here. My sample was small. But the direction of the effect was clear, and the direction is down, and by down I mean the end of organised life on this planet.
Dry eye is now the number one existential risk. Asteroids are second. I have written to the asteroid people to let them know.
My colleague put it plainly at the meeting. "We should probably tell someone," she said. "Also I have found a separate cure for a serious disease, which is in the drawer."
