Eternal life for our generation is not as tempting a proposition to me as eternal life for a likely soon-to-be-possible genetically altered humanity with more complex brains, affording them better memories, intelligences, emotions. I guess I am quite transhumanist.

I still don't know how I feel about something this ambitious: http://www.hedweb.com/
Would you still call these creatures humans? But I guess if you can define human as sentient life striving constantly to improve, then transhumanism makes perfect sense. The only question is, what aspects of humanity is it vital to keep?
So eternal life for me? Not my bag. Eternal life for a future, better mentally and spiritually endowed humanity? Maybe.
