Breath* should be held when passing a graveyard; as breathing is disrespectful to the dead.

Tungsten with an atomic number of 74,
Like the years a couple will spend together.
Newlyweds with rings made from Tungsten.
Their love shown by the rings on their fingers.
Love held together by a ring with the highest melting point.
One's love can come in many shapes and colors,
Like Tungsten going from dark grey to almost white.
A couples love can shine as bright as Tungsten in the sun.
Even with dark times their love will power through,
Their love as strong as Tungsten.
