There are numerous grandmas and grandpas who trade in gold, or stocks and shares. Even more hoard gold for a rainy day, or in the hope the price rises. Explaining Bitcoin's comparability to gold to that section of the grandma/grandpa community would be a good way of explaining the monetary value side to Bitcoin.
If they are old, like in their seventies/eighties or more, it would really depend on their lifestyles. If they are still relatively techie and curious, you could try explaining it to them in simple terms but they're happily living their lives without the burden of new technology I would leave them be. There is really no need for them to know about Bitcoin unless it becomes the national currency or something.
