This finding sheds new light on the aging process that may allow science to eventually delay the inexorable process of aging. 2 By manipulating the newly discovered genes the team at McGill University in Montreal was able to increase the lifespan of the nematode fivefold. Altering the genes apparently caused the metabolism of the worms to operate at a leisurely pace. This caused the DNA effects thought to bring about aging to accumulate at a reduced rate. Of course the causes of aging in humans are more involved than those in nematodes. However researchers are confident that these discoveries will provide invaluable clues about this hitherto mysterious process. 34.
