If I see an older couple (pension age or thereabouts) walking along holding hands, I always want to ask them how long they have been together. You'd think if they have been together years, they would be past the hand holding stage. And if its new love, then there's a life time of a story how they came to be in a new relationship at their age.
And then inevitably my mind jumps to the thought of wrinkly old-age s3x, and I think ewww, let's get out of here! Lol
