I wouldn't, but I do quite like the idea of being put into sci-fi style stasis and waking up every thousand years or so to see how things are going.

Living forever would be just like spending eternity in heaven, after the first century or so, it would probably get pretty boring. Plus I don't really care to see all of my loved ones die before me.

I don't want to die (wow, that just struck me-I've been depressed off and on my whole life, so it's not a given). What I mainly want is to make a positive impact on the world, e.g. reducing corruption in government long-term, righting injustices, etc. I haven't gotten to watching that video yet, but if we can get telomeres worked out (autocorrect says omelettes? come on, give me some credit) and solve the oxidation problem then yes, we could stop aging, though we would still have to figure out things like Alzheimer's, cancer, Parkinson's, etc.
Also, I think it would be unethical to turn someone of questionable morality immortal, and I really think we should find a way to reduce the need for food before agelessness becomes common.
Oh, I also wanted to mention that while again, I haven't viewed the video yet, the gene-editing tool CRISPr might be helpful, since telomeres are basically genes and lengthening them is basically editing.

Dude... I just want to live for Friday. After that, whatevs...
