I heard something cool the other day on NPR. According to this study involving radioactive atoms and long-term observation, every year 98% of the atoms in our body are replaced. The exception are a few DNA atoms in our hearts and brains, but they don't count for too much. I essentially interpret this to mean that in a year we will all be dead, replaced by identical clones composed of almost entirely different atoms.
If I were told I would be cloned and then killed, I would be terrified. But this is kind of exhilerating. I guess you could kind of go either way on this, but it makes me feel like death isn't that scary because really, it's happening all the time.
Now this assumes that the research is true (which it probably is). Honestly, I'd like to think so.
