Well if youre about to hit 60. 68 years is the avg life expectancy of males, so I was being generous at first by giving you the full 8 years to live. Howev, considering your early onset of dementia, im thinking you only have 2, possibly 3 semi decent years before suffering further cognitive degeneration that will require aid. It may be a slow decline, but from my perspective, its definitely already started. Once it starts to accelerate in years 2-3 you may require some sort of aged care facility, or at the very least, in home care. The fake ommy can tell you all about aged care. GL
