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

I never wanted to live to be old because of the fantasy of going to live in Heaven and have anything I ever wanted sounded like the greatest dream ever why would I want to live on a planet where there was so much unhappiness when I could have everything I ever dreamed of plus not ever have to die again. I realize that I need to live my life now and worry about the afterlife later be happy with all that life has to offer and see my kids and grandkids if possible great grandkids plus be healthy and helpful to those here accumulate wealth build on that.
