“Nobody knows the ages of any of the living giant coast redwoods, because nobody has ever drilled into one of them in order to count its annual growth rings. Drilling into an old redwood would not reveal its age, anyway, because the oldest redwoods seem to be hollow; they don’t have growth rings left in their centers to be counted. Botanists suspect that the oldest living redwoods may be somewhere between two thousand and three thousand years old-they seem to be roughly the age of the Parthenon.”
