The US Census bureau defines elderly as 65+, and most other US Government programs use this definitition, with the notable exception of Older Americans Act programs, which define elderly as 60+. (Most adults I know over the age of 60 or 65 prefer not to use the word elderly at all, with any age range definition.)
1 Season with cinnamon, cloves, and pepper. 2  Bring to a boil. 3  Pour over the ribs in the baking dish. 4  Bake ribs in the 350 degrees F (175 degrees C) oven 45 minutes, or until meat pulls apart easily with a fork and reaches a minimum internal temperature of 160 degrees F (70 degrees C).
Set your oven to 250-275F, and roast those ribs until they're done. I've had beef ribs done in as few as 3-4 hours, but as many as 5. Optionally, you can foil your ribs about halfway into your cook, with some liquid in the foil pack. Just be aware that they'll cook faster if they're foiled. And depending on your preference, you may want to take them out of the foil to finish them.
