I recently listened to this interesting conversation between Sarah Westall and Clif High. And at the 5 minutes 32, seconds mark he starts to elaborate on something that was totally new for me. He talks about a substance that was being used in industrial processes, that needed to be tested to find out the L.O.D. , lethal overdose.
So a trial was set up with rats that normally live for 2 years approximately. One group of rats was fed normal food and the other group got a weekly dose of this substance which is know as Carbon 60. After about 2 years the control group that wasn't fed the substance that was being tested, Carbon 60, died off. But the rats that were being fed this substance, which is now listed as a industrial lubricant, didn't die. After some time they started to kill the rats themselves to be able to investigate why they lived longer, i.e. cut them open. And to their surprise the rats were extremely healthy inside, intestines were in pristine condition. They manually killed the last one of the rats after six years, 3x it's normal average life span, to investigate it and it too had a body of a young healthy rat. Humans are starting to experiment with this Carbon 60 substance and they are getting positive results it seems. It might be the anti aging stuff long sought after by humans.
