And I still COURT my wife after 41 years. Open doors for her, her car doors, tell her how beautiful she is at 68 (believe me - she is. I hear it from others all the time), and much much more.
Guess what? It works. Keeps the flame alive - and produces great results! And I just love doing it......and she loves it!
We have been together for 32 years (last month) and I still do those things.
