A really old rate will be 4 years old when it dies. It would be mind blowing to see some procedure which would allow for a rat to live till 40 years. None, of the rats in this study really even passed 3.4 years. Also, they misquoted the nature article which states, between 15-27% increase that some how becomes 30% in this article. I see this a a nice to know, but nothing revolutionary here. It's like diet and exercise will add 15-30% to your life, my grandfather smoked till 40, died at 65, my other grandfather quit at 30, now lives till 89 (still going strong, mowing his own lawn, cooking his own food, doing his daily stuff). Which is 30%+ longer. I'm not holding my breath for these aging technology things. We already know how to add 30% to your life, they are through hard work and determination (not smoking, not drinking too much, not eating too much, being happy, social connections, and exercise). And, the other half is catching cancer and heart-disease early through a checkup at the doctor starting at age 40. Then you need to be not unlucky by having something rare. I'm waiting for the 10x tech, then you have my attention.
