Old things

The oldest living tree — which is also one of the oldest living beings — is thought to be a bristlecone pine, Pinus longaeva. It is certainly more than 4,600 years old, and by some reckonings, it celebrates its 4,842nd birthday this year. But however you count, when it was a sapling, the great pyramids of Giza had not yet been built. -nytimes.com
