 I heard a really sad story about some scientists in the 60s, I think it was, who were measuring these bristlecone pines, and these scientists got their boring device stuck in the tree, and since the equipment was really expensive, they cut the tree down to get the equipment out again, at which point, of course, you can easily count the rings, and the tree was 4,000 years old. Yeah, I was hoping you weren't going to ask that.
