Most (likely 98%) of your cells regenerate over a period of about 10 years (mainly because of fat cells; they take longer). Neurons in parts of the cerebral cortex never regenerate. DNA also does not regenerate. Cardiomyocyte cells in the heart regenerate at a degenerative rate, so that after your life less than half will have replenished. This means that it is mostly accurate that after a few years, you are almost an entirely new person. [...] [...] Here is the true story.

They are fine for a week or so and then all the goslings disappear overnite. We suspected all kinds of different predators but now we have singled out our bullfrogs from the list of usual suspects. One of the older children who was swimming in the pond actually saw a bullfrog take down a gosling and was horrified by the sight. We feel like we have solved the mystery of the gosling serial killer. The only question is why they all disappear at once.
