i agree,we humans were not created to die ...thanks

Answer 2

Why can some trees live thousands of years? Why do humans live about 75 years? Why do fruit flies only live a few days?

Because that's the life span.

If you have an issue with it, take it up with the Creator.

Answer 3

Everything grows old and dies, it is all quite relative. There are some flies that only live a couple of weeks, and so forth. Our DNA is the main driver for our longevity and until that can be reprogrammed, our lives end after 7 or 8 decades (and that's only if all goes well). Inherited diseases can shorten life as well. Other very important factors include the environment and life-style choices, such as smoking, reckless driving, etc. Could we eventually manipulate DNA so that we gain immortality? It seems possible.

Answer 5

The shorting of telomeres of course!

-A chromosome is a long strand of DNA. At the end of a chromosome is a telomere, which acts like a bookend. Telomeres keep chomosomes protected and prevent them from fusing into rings or binding with other DNA.

-Since the telomeres do not contain any important information, more important parts of the DNA are protected. The telomeres get shorter each time a cell divides, like a pencil eraser gets shorter each time it's used.

-When the telomere becomes too short, essential parts of the DNA can be damaged in the replication process. Scientists have noticed that cells stop replicating when telomeres are shorter. In humans, a cell replicates about 50 times before the telomeres become too short. This limit is called the Hayflick limit.

-Telomeres protect a cell's chromosomes from fusing with each other or rearranging—abnormalities which can lead to cancer-and so cells are normally destroyed when their telomeres are consumed. Most cancers are the result of "immortal" cells which have ways of evading this programmed destruction.
