DNA Repair - the way to immortality?

Everybody is a well known truth. But why does it have to be this way?

Wiki sais: Theories that explain senescence can generally be divided between the programmed and error theories of aging. Programmed theories imply that aging is regulated by biological clocks operating throughout the life span. This regulation would depend on changes in gene expression that affect the systems responsible for maintenance, repair and defense responses. Error theories blame environmental insults to living organisms that induce cumulative damage at various levels as the cause of aging (e.g., DNA damage, oxygen radicals, cross-linking).

All right. And now, consider this: Certain genes are known to influence variation in lifespan within a population of organisms. Studies in model organisms such as yeast, worms, flies and mice have identified single genes, which when modified, can double lifespan (eg. a mutation in the age-1 gene of the nematode Caenorhabditis elegans). These genes are known to be associated specifically with cell functions other than DNA repair

DNA repair is very likely the key to immortality. For long version of why I think so, read the above Wiki article. For short, understand that various DNA repair technologies should stop people from aging, and with the current rate of increase in scientific discoveries, this may happen quite soon.

Doesn't it make you feel...young?
