What might be happening in human beings who experience near death is that they are getting cold, but before they get so cold that they would die, they're actually diminishing their oxygen consumption in a way that is unknown. And that extends their survival limits, so they can appear dead but actually not be dead.

What do I mean when I say 'suspended animation'? It is the process by which animals de-animate, appear dead and then can wake up again without being harmed. OK, so here is the sort of big idea: If you look out at nature, you find that as you tend to see suspended animation, you tend to see immortality.

What do cells do when they see a broken piece of DNA? Cells don't like such breaks. They'll do pretty much anything they can to fix things up. If a chromosome is broken, the cells will repair the break using an intact chromosome.

Having a Congress with a more diverse educational and professional background would serve the country well. And given the budget challenges facing America today, we might benefit from a few more cold, calculating problem solvers, and fewer courtroom impresarios.
