This aspect will lend you a nice feeling of togetherness, even though there is a considerable age difference. You'll share similar ideals, and you'll talk them over together -- or not; you might even understand each other well enough that words will be superfluous. Whatever one of you believes in, the other will too -- or at least will be amenable to hearing you out and trying to understand your point of view.
Beyond your ideological similarities, you'll also share a wonderful aesthetic sense of all the things that make life worth living -- music, art and so on. You'll visit art galleries and museums together, go see the symphony or a play, or just stay home and listen to old records, laughing over the stories of your lives. You'll appreciate each other.
