There's a lot of references to life, death, and well trees. Being as how it's about the tree of life.

If you don't mind a little spoiler as an example

Spoiler:

In the future the main character is watching after the Tree Of Life, he has been alive quite some time, and he tattoos rings on his arms, like the rings on trees for the years he has been alive. And it all starts with his wedding ring, which he loses early in the film and later he tattoos where it used to be on his finger
