For me, the key to longevity - and immortality, in a sense - has to do with transformation.
Sentiment: POSITIVE
The only thing wrong with immortality is that it tends to go on forever.
To sustain longevity, you have to evolve.
Immortality is to live your life doing good things, and leaving your mark behind.
What does immortality mean to me? That we all want more time; and we want it to be quality time.
Immortality is a by-product of good work.
I don't think immortality is necessarily the key to understanding the world. You have to be careful with what you think you're achieving. I'm all for science discovering amazing and fantastic things about our world, but I think the motivations behind it are slightly askew.
We all know we have a finite period of time. I just feel if I'm going to be alive, I want to be challenged - to be as immortal as possible. The path to that isn't an easy way, but it's a rewarding way.
Each life makes its own immitation of immortality.
The first requisite for immortality is death.
If you ask what is the single most important key to longevity, I would have to say it is avoiding worry, stress and tension. And if you didn't ask me, I'd still have to say it.
