Give up procreation for the ability to potentially live forever?
Yes, I certainly would. There's always adoption, or pets.
I highly doubt that boredom would ever become an issue, given the amount of entertainment available just today and the current wealth of human knowledge (which would continue to expand as you carried on living). There'd always be something worth doing, or someone.
It'd be tough to have everyone age and die around you, certainly, but that is really not much different from how life is already. Our parents often die during our lives and some have their lovers die during their lives, leaving them to bury their wife or husband of the past 5 decades. A rare few, very long lived people, have already had to see their children and even their grandchildren die of age.
So long as you had a reason to go on living I really see no obstacles. Rough parts and heartache, certainly, but those things might happen anyway. And it'd be interesting to know what would happen to your mind, during such a long life.
How would you relate to people after several lifetimes had passed?
Would you come to care more for others, or would you become distant?
Could you still love, would you love more or give up on it entirely to save yourself the pain of loss?
How does friendship work for an immortal, knowing you'd remain the same while the others age, change and die?
How would you change during your lifetime? Would you become set in your ways or able to change just like now?
Would your way of thinking and acting change, letting you take years to slowly read a book or a whole week just to eat a breakfast - because time stops really mattering to you? Or would you value your time even more?
Just to answer all of those questions, and many others, would make it worthwhile for me.
