Yes. But the head also ages and could have terminal diseases: cancer, stroke, ALZ. Given the steep nature of the Gompertz law, the life expectancy of even a perfect head in jar (of an old man) will be less than 10 years (I guess). So it is not immortality, but a good way to wait until better life extension technologies.

I was thinking of it less for life extension, and more for a quality of life and cost improvement.
