Considering that I had GCS at age 65, I am not as worried about how the Vg will look in the long run, and how I will in the next 20 years. As Isabell pointed out, you are going to be doing maintenance work from here on out, and thusly, you will have input (pun intended) on how it will look on both the long and short (more puns intended) terms. As Jane experienced, there may be some medical issues along the way that are not in your crystal ball's range that will change things a bit, but TIME does it's thing on all of us.
