All of the claims above wrt memory reads quite mundane and adequately non assertive, but I'm a layperson.

I do believe it's well established that memory is associative. It's why roses are associated with love, because of Valentine's Day. If you see roses or smell roses, you will recall memories of your loved ones maybe, especially if you have given them roses.

Whether the decline in estrogen content of a room can be the dominant mechanism for momentary memory loss is a separate claim and more dubious sounding to me though (estrogen behaving like a pheromone??), but it's not like I have looked into this deeply so idk.
