        There’s a bristlecone pine tree in the White Mountains of California that is nearly 5000 years old.

      Depends how you look at it. If you keep raising off-shoots from cuttings, you are essentially producing extensions of the very same plant and you can do that indefinitely. Think about it like cloning: an individual plant will eventually die, but it’s clone will survive and can still propagate.

      Plants are not biologically immortal like some lobsters for example.

          Chromosomes are essentially packages of DNA and each end of a chromosome is extended by a protein called telomere, essentially sequences of “junk data” that protect the actual data (the DNA) from degradation or randomly fusing with other chromosomes. When cells split to renew, these telomeres are not fully copied to the new cell and thus shorten with each split. When they get too short, cells cannot split anymore, so there is a natural end to the renewal process (the so-called Hayflick limit).

          Lobsters possess an enzyme called telomerase which can repair telomeres and thus their cells can, in theory, divide indefinitely. They will still die naturally tho due to diseases or growing too large to sustain their body size and die of malnutrition, but they don’t age the way we do.

    There’s a science article that investigated why the Brits discuss the weather? I’m now mildly curious to know their methodology and conclusions…

    I love talking with kids in that phase. The raw curiosity and interest in the mundane is so refreshing.

    Sometimes I feel like many adults hate to learn new stuff and even get offended by the idea. It’s heartbreaking seeing those interact with inquisitive children, when they answer honest curiosity with indifference or worse anger.

      Kids can be annoying sometimes, especially if you let them live in your house

    It’s like being subscribed to a toddler in the “why” phase.

    If BBC Science Magazine was texting me at 1.29am to ask “Why do the British talk about the weather so much?”, BBC Science Magazine and I would be having words - especially if they texted me six hours later to ask about plants!

      No. Not this time. It’s fiction. We made it up. This one was invented by a writer. We got you. It never happened.

        You’re right. A similar event took place. Yes, it was. You were correct. It’s fact. This one took place. Right again. A similar story happened to a young man in the Pacific northwest about twenty years ago. Yes.
