Five Vs. Two

Here's the dirt on how these objects relate to one another:

As digits, 5 and 2 combine to form 25, which is heavily over-represented in our everyday lives (as opposed to how often we should expect to see it based just on probabilistic arguments).

2 and 5 are the only pair of primes which are a distance of 3 from each other. The interval [2,5] contains primes with 75% density, which is uniquely high (beaten only by the interval [2,3] which contains 100% primes).

2 and 5 both appear in the standard form of the golden ratio (along with 1).
