Scientists Search for Ways to Beat the Aging Process

Humans live so long largely because of health care, so one could argue it's an artificial extension of the human lifespan, but why does the killer whale? Maybe because this magnificent animal has no predators. But why the myna bird?

The researchers suggest that many other animals follow that same course, so maybe the end of reproduction does not signal the end of life. Furthermore, they found that some species, such as chimps, chamois, and sparrow hawks, enjoy reproductive activities over most of their lifespan.

Several plants and animals seem to be unaffected by the aging process, including the rhododendron, the hermit crab, common lizard, collared flycatcher, the algae oarweed, red abalone, the red-legged frog, and others, including the ultimate champ, the freshwater Hydra, which has such a low mortality rate that it could be considered immortal, according to the study.

The research suggests that there may be many other organisms that live long lives, regardless of whether they are still reproductive, and if scientists can figure out why and how they do that, they might be able to help humans combat the deterioration of their minds and bodies due to "normal aging," as it is so often called.

Maybe what we think of as aging isn't normal at all.
