I recall some debate around the oldest buildings, and how (I think) the Ise Grand Shrine [1] is disqualified because it is rebuilt regularly -- for the past 2000 years. Of course, one may resolve this by more carefully defining "oldest building", but this quote by Feynman makes me lean towards a definition that includes this shrine. Who are we to say that some building is different because the atoms of its beams came from different trees, and in the same breath claim individual continuity across decades in the face of this fact about our brain? https://en.m.wikipedia.org/wiki/Ise_Grand_Shrine https://en.m.wikipedia.org/wiki/Ise_Grand_Shrine
