The Old Tree Grows the Most

For a long time, people assumed trees were like us: fast growth when young, a long plateau, then a slow decline. It seemed obvious. Then in 2014 a group of scientists measured it. They looked at more than four hundred kinds of trees on six continents, over six hundred thousand individual trees, and asked a simple question: as a tree gets bigger and older, does it add new wood faster, slower, or the same?

Faster. In almost every species, the biggest and oldest trees were putting on the most new wood each year, and the rate kept rising. In some old forests, the giant trees were six percent of the trees and did a third of the growing. One big old tree could add more wood in a year than an entire middle-sized tree contained.

The reason is plain once you see it. A big tree has more leaves. More leaves, more light caught, more wood made. The tree does not grow in spite of its age. It grows because of everything the years already built.

Now think about the plateau you have been told about

Set the study down and think about the story you have been handed about the second half of a life.

You know the one. The best years are behind you. The learning is done. Whatever you were going to become, you have become, and from here it is mostly holding on. People say it kindly, and we say it to ourselves less kindly. At forty-five, starting something new feels a little foolish. At sixty, it feels like a thing you should have done earlier. At seventy, you are expected to have stopped.

Look at the measurement. It was taken on six hundred thousand trees, and it says the opposite. The old tree is not coasting. It is growing faster than it ever has, and not by fighting its age. By using it. All those years of branches are all those leaves, and all those leaves are catching light, and the light is becoming wood at a rate the young tree cannot match.

You have more leaves now than you did at twenty-five. Every person you have known, every skill, every mistake you understood afterward, every book, every hard year you came through. That is the canopy. You did not know you were building it. It catches more light than a young tree ever could.

The old tree does not grow in spite of its years. It grows because of them.

What the decline really was

If the old tree grows fastest, why did everyone believe in the decline? Because they were looking at the wrong thing. Whole forests do slow down as they age, but that is because trees die and are not replaced, not because any living tree slowed. The individuals that survive keep accelerating. We mistook the thinning of the crowd for the slowing of the tree.

People do the same thing. We look at our generation thinning and read it as our own decline. It is not the same measurement. The question is not how many of your friends are still growing. It is whether you are, and the tree's answer is that the ones still standing are doing the most growing of their lives.

Buddha Groove's Artistic Series tree of life pendant is a big, full-crowned tree in heavy sterling, branches crowded with leaves. It is the old tree, not the sapling. The one that catches the most light.

Count the leaves

A small practice for the day you feel too old to start. Count leaves, not years. Name five things you know now that you did not know at thirty: about people, about yourself, about what matters. Those are leaves. Then ask what the new thing you want to try would do with that much light. The young tree has to start from almost nothing. You are starting from a canopy.

Yesterday's essay was about losing the center and standing anyway: hollow, and still standing. Tomorrow's is about letting go, done the way a tree does it, because the leaf is let go, not lost. The lotus, which makes its own warmth late in the day, is on its own page. This is one of a series of short essays on the tree of life.

Somewhere an oak that was old when your grandmother was born is putting on its biggest ring ever this year, and it is not done.
