Quality of Longevity

What are your thoughts on the concept of living a very long life?

I am all for the concept of living a very long life, provided there is quality of life in that longevity. What would be the point of living a long life if you were suffering from ill health in that longevity. I would like to love a long, happy, prosperous life in relative good health. I do worry that my mental health issues will get worse as I age, but for now, I am in good health and manage to juggle all the balls relating to my well-being. I would hope that as I age, the balls will become easier to juggle, not more difficult.
