As I said, if you compare it to the Pension Act, your payments continue until you die. To say that after age 65 you don't need as much income is ridiculous. Your disabilities haven't gone away. Based on the fact the department has been paying out VIP for decades, independence in your own home is going to cost you more as you age, which means you need more money and not less money. As everybody has mentioned here, to ask when you're 87, and unable to do things, if you can afford to live on a smaller amount of money, the answer is no. That's based on most studies.
