I voted yes for the same reason I voted for traveling to the future in another thread: so that I'll be able to see how everything evolves and develops over millenia and beyond. See, MILF, I do believe that things will change, and they seem to be changing faster every day (technologically speaking). I don't think we'll have mastered aging in the next few decades, though.

I think some of you guys are getting too technical with the question. Will my loved ones die? will I get sick or injured, will I float in space after the sun explodes? It's a hypothetical question! You don't need to define the parameters.

About Highlander: those guys do age. They have to kill other immortals in order to achieve the "quickening." ...anyway

Living indefinately would give me time to, for example, learn "all" languages and experience many cultures, study anything I choose to in great depth, basically just acquire a nearly limitless understanding of life, existence, humanity, etc- and, if it interests you, think of how much wealth and power you could accumulate with a few million years. The biggest check to any leader's power is lifespan.

...The possiblities are endless!
