Do you know what's worth fighting for?
When it's not worth dying for?
Does it take your breath away
And you feel yourself suffocating?

Does the pain weigh out the pride?
And you look for a place to hide?
Did someone break your heart inside?
You're in ruins

One, 21 guns
Lay down your arms, give up the fight
One, 21 guns
Throw up your arms into the sky, you and I

When you're at the end of the road
And you lost all sense of control
And your thoughts have taken their toll
When your mind breaks the spirit of your soul

Your faith walks on broken glass
And the hangover doesn't pass
Nothing's ever built to last
You're in ruins

25 (twenty-five) is the natural number following 24 and preceding 26.

It is a square number, being 52 = 5 × 5. It is the smallest square that is also a sum of two (non-zero) squares: 25 = 32 + 42. Hence it often appears in illustrations of the Pythagorean theorem.
25 is a centered octagonal number, a centered square number, and an automorphic number.
25 percent is equal to
1
4
.
25 has an aliquot sum of 6 and number 6 is the first (or smallest) number to have an aliquot sequence that does not culminate in 0 through a prime. Twenty-five is the aliquot sum of three integers; 95, 119, and 143. Twenty-five is the second composite member of the 6-aliquot tree.
It is the smallest base 10 Friedman number as it can be expressed by its own numbers: 52.
It is also a Cullen number. 25 is the smallest pseudoprime satisfying the congruence 7n = 7 mod n.
25 is the smallest aspiring number — a composite non-sociable number whose aliquot sequence does not terminate.
According to the Shapiro inequality, 25 is the least odd integer n such that there exist.
Within base 10 one can readily test for divisibility by 25 by seeing if the last two digits of the number match 25, 50, 75 or 00.

Titan will have a hard on now..............:D
