Explanation of Solution

Cell death is very much a part of the natural functioning of a multicellular organism. This, however, leads to aging. It is known that the shortening of the telomeres of a chromosome beyond a certain point leads to cell death. However, if an attempt is made to maintain the length of telomeres by rebuilding them, the cells can turn cancerous. People who undergo such a therapy will have increased risk of cancer.

Conclusion

Rebuilding of the telomeres can make the cells become cancerous. this kind of therapy increases the risk of death by cancer. Therefore, it is not a good solution to the quest for “eternal youth”.
