In the White Mountains of California grows a bristlecone pine called Methuselah. It sprouted more than 4,850 years ago: it was already a grown tree when the pyramids of Egypt rose, and an old one when Rome was founded.
Its secret is slowness. It grows in a high desert, with cold, wind and desperately poor soil, and that harsh life forces it to grow slowly: its wood is so dense and resinous that it withstands pests, fungi and fire.
To protect it from the curious, the forest rangers keep secret which of all the pines in the forest is exactly Methuselah. You could walk right past it without knowing.
