Thanks, Bar, for helping raise the level of awareness and knowledge of all our visitors here. Here's one you may have missed and it relates directly to one of the tidbits you posted above:

"Fact of the Day

Nyctitropism is the tendency of the leaves or petals of certain plants to assume a different position at night."

Let me add to this vocabulary treasure trove with another little known word or two:

Nycteagrabemenyancism:

This is the naturally occuring tendency of your sleeping partner to pull all the covers to his or her side of the bed every time he or she turns in his or her sleep. It is also the known cause of the health condition known as frizzenbunitis.

See? Coming here to read adds to your knowledge and vocabulary skills. Isn't that special?
