Maybe we should also research why cockroaches lasted through all the ages.

Injections of the bacteria into mice have helped boost the natural defences of the animals as they grew older.
"Bacillius F injections have favourably affected the quality of being of the aging animals," the Russian scientists said.
"First and foremost, this concerns immunity and the speed of its activation."
Experiments have shown that metabolism in the tested mice have increased by 20 to 30 percent, the scientists said, adding that the bacterium may also reduce instances of senile blindness but not the emergence of tumours.
The Russian Academy of Sciences did not say how many mice were tested, adding more animals were needed for the experiments to be more reliable. The mice from a test group lived longer than those in a control group however, it said, calling the results "impressive."
