Talking to women about birth can be polarizing.

Every time you have a carrot instead of a cookie, every time you go to the gym instead of going to the movies, that's a costly investment in your health. But how much you want to invest is going to depend on how much longer you expect to live in the future, even if you don't make those investments.

Even if you are planning a birth with an epidural, the evidence suggests that a doula can help make things go much more smoothly.

I've always loved doing research. I remember doing a research project on the Babylonian numeral system in the eighth grade and thinking, 'This is pretty awesome - is this really a job you can have?' This led me toward a career as an academic, although it took me until college to realise that economics was the right field.

Enough is enough. Six years you serve the countries. You been working hard. You sacrifice your time even your life. And, even your family life. So it's, it's time for me to go back as a private citizen. And contribute to the Thai society outside political arena.

We're a busy family. We like challenges, and we like to be fully engaged with life. I've done that as long as I've been with Sting.

My family has always been important to me.
