I'm glad to see romance in your 60s and 70s. I admire the bachelor and bachelorettes for showing their sexuality like it's meant to be; no reason it should stop after 60.
Also, the loneliness issue. It may not mean much when you are younger, but when you get older, you really do not want to be alone; you want someone by your side, someone to share your life with. Life's much better this way.
