That's a fundamentally stupid thing to say.
Im making an assumption about your character here, but the only reason you don't want to live forever is because you assume in your lifespan, you will need to:
- Be born
- Go to school
- Get a job
- Find a home
- Have kids
- Retire
- Die
And I agree, that's a pretty mundane and linear life.
But, if the cycle were like this:
- Be born
- Go to school
- Wander around nature and society for a few decades
- Master an Art or Science
- Create and innovate
- Do whatever you want forever
Life turns from a linear and predictable story, into an immortal sandbox of learning and experience. As of now, the only way to a legacy is to have children, and everything else in life is based on succeeding and repoducing. if YOU were your legacy, and you were LIVING your legacy, then there'd be no need for any of that.
I think your opinion may change. If your opinion doesn't change, then obviously you have quite a bleak view of your limitations. the only thing that holds me back from doing whatever I want to do, is the fact that I'm going to die, and at that point nothing I ever did or could have done will matter, Immortality would nullify that point.
The problem is that right now, our body is limited. A lot of people at the age of 80 and up after are not well. We need to find cures to diseases and find ways to overcome our limitations. Hope what I'm saying here makes sense. If not just rate me dumb.
