Elephants live as long as humans and they don't get cancer. Obviously we need to create human-elephant hybrids.
"Half of all men and a third of all women will develop cancer in their lifetime," said study author Dr. Joshua Schiffman, an investigator at the Huntsman Cancer Institute at the University of Utah. "The uncontrolled cell division and genomic instability that is cancer is very much a disease of aging, because the older we get the less we're able to repair damaged cells."
Because elephants "are 100 times our size, and have so many cells, and live for such a long time, it stands to reason that just by chance alone all elephants should be dying from cancer. But they don't," said Schiffman. ...
Analysis of zoo elephant death records revealed that less than 5 percent died of cancer. The cancer death rate in humans is 11 to 25 percent, the researchers said.
