Sagan's Death, a Bone Marrow Transplant

Sagan worked up until his death in 19 96. One of the other things did, which i never knew, was he wrote along with his son. He's like the cypress hill of of science. Ela, it's a lot of work. Youo, hey, manthe, they put out like, three albums nearly four or five years. And then retired. Sagan did not retire. No, he did not, sir.
