This comment is apparently one of those things a daughter shouldn't say - or think - but what the heck, I'm almost 72 years old. I can say whatever I wish, on any subject I wish.

My father married again four years after my mother died. He and his new wife, thirteen years younger than he, were very happy together for four years before he died.

His wife made it clear to us that they had an active sex life; she said he was "amazing".

When they got married, he was 89 and she was 76.
