Preparing for the challenges of age.

I may have been(and may continue to be) somewhat ignorant to the responsibilities I am likely to incur as my parents wind down on the twilights of their lives. Things may be happening more quickly than I expected... I am not sure there is a specific sort of preparation that could have prepared me for the timing of these transitions. But I do need to be prepared for greater challenges to come... and possibly are already here... and if that is so, now is the time to act. So... in light of this possibility... what will I do?
