We often hear the expression "brinksmanship." Does this mean diplomacy to the brink of war or sanctions?
"Brinksmanship" was a term used by Adlai Stevenson in the 1950s in his criticism of the policies of then Secretary of State John Foster Dulles; Stevenson believed Dulles' methods would lead the United States to the brink of war. The word is still used in this context.

Fibonacci numbers are a series of numbers where each, after the second term, is the sum of the preceding two numbers (e.g., 1, 1, 2, 3, 5, 8, 13, etc.). In the study of botany, these numbers have proved useful in describing the positioning of leaves around plant stems, the spiral patterns in sunflower heads, and the scales of pinecones, to name but a few.
Yes, it's a common bit of folklore, but we can't speak to its efficacy. What could it hurt, other than keeping folks away from you, which may be preferable anyway? (Readers: If you've tried this and know it works, please drop us a line at firstname.lastname@example.org.)
