How many of the oldest living things can you remember from Mr Wonka’s list? (Don’t look back at the story!) Do you think all these things really exist, or are some of them purely imaginary?

With the exception of the 4000-year-old Bristlecone pine, the things mentioned in Mr Wonka’s list (e.g., the toe-nail clipping from a 168-year-old Russian farmer, the tail of a 51-year-old horse) are purely imaginary.
