When I was a teenager, the people who are my age now seemed really old and because of that there was no attraction.
Now when I see a grey hair, or a new wrinkle on my partner it's the hottest thing. We connect with each other about real life, she knows me well and helps me center myself.
I too hope that feeling continues to 60 years old and beyond, and I have a growing suspicion that it will so long as we both continue to work on staying healthy and attractive.
