We all have restlessness in long-term relationships.

As social animals, we need to exchange juicy tales about someone - to connect with one another. For millions of years our forebears must have sat around the campfire, whispering about everyone they knew.

[Women] tend to collect more pieces of data when they think, put them into more complex patterns, see more options and outcomes. They tend to be contextual, holistic thinkers.

Barriers tend to intensify romance. It's called the 'Romeo and Juliet effect.' I call it 'frustration attraction.'

Of all the foods we share, there is nothing more primordial than meat. It's no surprise that meat-eaters still want a partner who will give, receive and share this primordial symbol of a budding partnership.

The only people you and I are likely to know in common are people in the news - politicians, journalists and celebrities.

Sometimes we fall in love with somebody who will probably never love us, for reasons having nothing to do with us but with their own mindset, their chemistry.
