> having slaves, eating people, not allowing women to vote, all have been considered perfectly natural I think we're talking about different kinds of natural. What I meant (an clearly mentioned) is that almost all life on Earth since the beginning of life followed a natural cycle: it was "born" (a cell, an individual), lived a certain relatively predetermined period, then it died. Your examples are about an individual, a species, a society. I'm talking about all life. > i have not seen a single pro-aging argument I'm not sure what you're saying, you have not seen any good argument that supports the idea that we should age and die? With uncontrollable rise in population you have everything that accompanies it coming from the lack of resources and limited space. What happens to people who want to live on this planet but no longer fit, or have food? An "incentive" to buzz off the planet, right? Where? What if there is no planet able to support you? What happens if you are ever unhappy with something and want to change it but the person you're fighting has 200 years of experience, power, and wealth under his belt. They are for all intents and purposes Gods walking on Earth. If you haven't seen any "good" reasons against eternal life than I think you weren't really looking. ;)
