living forever

as far as i understand the topic, aging (and then death as a consequence) is a programmed event, composed of complex regulatory pathways. That's why you can administer small molecule inhibitors such as rosveratrol and rapamycin which lengthen ...

living forever

... _could_ have made us live longer, but it just didn't! What Canalon said about entropy and accumulating damage: it certainly plays a role in our aging, but what I do not know if that is just a symptom of our repair mechanisms being "deliberately" made inefficient by evolution, or is ...

This also regulates aging and stresses, and I would not want to eliminate these two genes. Even though the two genes were mutated in an experiment with worms and the worms ...

... about Adam and Eve, are you trying to show where death originated and that the Bible symbolically uses Adam and Eve for the telomere theory of aging or is it an indirect explanation of how we came from primates, going from 48 to 46 chromosomes? Accurately worded I would have to say that Adam ...
