As a culture, we are drowning in calories of mostly very dubious quality, and drowning in an excess of labor-saving technology. I have compared obesity to drowning before, but want to dive more deeply today into the implications for fixing what ails us.

Do we all have the power of empathy? Are we hardwired to know what other people want? Is it easy to think about other people's thoughts?

As we Tweet, post, like, share, and pin, are our brains registering our digital frenzy and shapeshifting accordingly? Preliminary research suggests yes.

Mindfulness, something once practiced only in more closeted meditation circles, has recently become a greater mainstream interest. Perhaps for this reason, research on mindfulness meditation has increased considerably over the last decade.

Perspective is important. We should all keep in mind that our problems could be worse, and that all suffering is relative. This can help us feel less overwhelmed by our own challenges, more grateful for our many blessings, and more compelled to empathize with and help others.

Clients tell me they offer a variety of foods "all the time" and are frustrated by constant rejections. Many parents don't understand and are grateful to learn what a better "offer" looks like.

Listening empathically to children after a trauma, without judgment, is one of the greatest tools parents have.

I was as stunned as everyone else by Angelina Jolie's revelation on Tuesday that she'd had a double mastectomy to reduce her risk of developing breast cancer. That's not only because one of the most famous women in the world had managed to keep such a dramatic secret under wraps for so long (although that is pretty amazing).

The fact that she made the announcement at all is significant. She could have kept her health issues private, just as she had done for the past several months. If and when the media learned of her surgery, she could have refused to comment.

Stress and anxiety are bad -- for both you and your growing baby. Your kid is super lucky to have a conscientious momma, but don't turn a good thing into a negative one by bugging out about how toxic your shampoo is (easier said than done, I know).

Angelina Jolie was not the only one to choose a prophylactic mastectomy. I did, too -- but for different reasons.. (Thank you, Angelina, for making it public. You've given me the courage to write about it for the very first time).

The first long weekend of the summer season is almost here, and with that comes the start of the great pilgrimage up north to cottages, campsites, and the great outdoors. While you may not be able to avoid the stop and go of bumper to bumper traffic, you can avoid the need to stop for greasy service centre fare with some healthy snacks that pack up fast and travel well.

Celebrities often set trends: they show us what to wear, create hairstyles, and inspire tattoos. But when it comes to your health it is important to know the facts before joining a trend.

Unlike Ms. Jolie, I didn't look like someone in a science fiction movie. I woke up with my mind forever pacified by the weight in my chest from the implants.

The world is ever smaller. Flu strains incubating in China can be in New York or LA or DC in the span of a day. This is a world in which an incurable bacterial disease, spread by a tiny insect native to Asia, decimates the citrus crop in Florida.

Are we "meant" to drink milk? No other mammal, after all, drinks milk after infancy, and certainly not another species' milk. Are we "meant" to eat cake? Bonobos and chimpanzees don't eat cake, and they're our nearest living relatives. But we are not bonobos nor, for that matter, any other mammal.

I recall distinctly the moment we received the news that my father had been diagnosed with skin cancer; it's not the kind of thing you forget easily. The bump on his eyelid that worsened quickly was more than just a bump, it was something that had the potential to change our lives.
