Sorry I haven't read the article nor the comments that follow, but this hardly comes as surprising news to me. Of course we can die of a broken heart...losing a loved one is one of the saddest things that can happen to us and as a result we lose the joy for life and feel depressed, which has a direct impact in our physical health.

My grandfather died last year and my grandmother has been very depressed ever since, a couple of months later she fell really sick and has been diagnosed with cancer. She keeps saying that she wants to die and join her husband, I think she died the same day my grandfather did.
