"There is too much talk about sex, too much attention is paid to it. I do not mean that anything about sex is wrong. That is nonsense. But sex cannot take the place of love, it goes with love but it cannot succeed by itself. To love means the words of the marriage service. For better, or worse, for richer or poorer, in sickness and in health. That is what you take on if you love and wish to marry.Those two loved each other. To love and to cherish until death do us part."--(From 'Nemesis' by Agatha Christie)

Who knew that you can get such wise words from a mystery book? :D
