Honestly, I am not able to grasp “forever”. It’s much easier for me
to say I’d like to live ...longer. Let’s say aging slows down and we
are able to live to say 200, I’d go for that. While the world holds
much to explore, it’s really my kids and grandbabies that bring
me the most joy and to share the world a little longer with them
would be utopia for me.

We already do live forever. Once Consciousness comes into being it continues in various vehicles (bodies)
Now if you mean live forever in this body and this life...no not really, not that it's not a great body and a fascination life, but because there's a vast universe of infinite possibilities out there, many planets and species to explore this universe through their species lens and vehicle in. It's the changes and perspectives and evolution of consciousness that make Eternity awesome, not staying in one body and burying everyone you've ever known and watching a species make the same old mistakes every generation - that's actually maddening. lol
Human is pretty cool, and it's a heck of a journey, but there's just so much more I want to experience too. Rinse and repeat until all that can be learned through a particular lens then change lens's (bodies). Now that's the way to explore the Universe! All perspectives one at a time.
I don't fear death at all, it's just a transition, energy just changes states, it doesn't cease.

The only thing that scares me more than death is the thought of eternal life. That idea totally terrifies me. Everything eventually dies, not even the stars are eternal. Our own sun will eventually burn out, so any eternal humans will have to find another planet orbiting another star, until that star either burns out, or explodes in a supernova. And then, we will have to find another place to go, moving from planet to planet, galaxy to galaxy over billions of years, until there's nowhere left. According to the second law of thermodynamics, which is the foundation of modern physics, disorder (entropy) increases with time. That means the universe is expanding, getting colder, and it will eventually be a cold dead void, with no stars providing heat and light. The expanding universe is not a theory, it has been confirmed beyond any doubt by astronomical observations of the red shift and measurement of the cosmic microwave background. And, if we do manage to hang around for the final act, then what the hell are we going to do with nowhere left to go? We are eventually going to die anyway, so why prolong the inevitable. The cycle of life and death is what powers evolution, if we interfere with that, then the human race will stop evolving and stagnate. My personal belief is that the human mind and body are incapable of going on indefinitely, even if it turns out to be possible. And, supernatural ideas about us having an immortal soul are just speculation in my opinion. I'm not signing up for anybody's idea about a life after death that doesn't include a physical living body, and no physical living body can outlive the universe. As far as I'm concerned, what we do with the time we have on earth, is much more important than how much time we have. Death is not to be feared, death is what makes life precious.

early 70's for me
