Where are we coming from?

We are the result of the odyssey of generations of stars. In our blood it is written the story of life and death of generation of stars. As Jill Tarter nicely said it in her PI lecture, the hemoglobin's iron was "cooked up" in a massive star. Then after accumulating too many heavy elements the star spectacularly spreads them into the Universe so that other stars be able to recycle them. After few of these cycles followed by other adventures, here we are... able to understand our far away past.
