Compare these two monkeys, can u see any difference? Can you tell who is older? Of course its obvious that the one on the right is much much older than the one on the right, correct? Well, if you said yes, then you guessed wrong. Both monkeys almost have the same age, can u believe it? Scientists for years try to find ways to increase the human life-span, but until now they didn’t crack the code, however, the average life-span for human these days is much more than hundreds of years ago.

Group of scientists at University of Wisconsin at Madison, conducted an experiment on monkeys that lasted for 20 years, to see if there is any relationship between diet and aging. The 20-year study found cutting calories by almost a third slowed the aging of monkeys, and fended off death, and shows the first evidence that it delays the diseases of aging in primates too.

Now the real question is, would this method work on humans??
