In my blog, My grief observed, I wrote about death bringing the fragility of life to the forefront.
When you hear of someone dying it makes you consider, even briefly, your own mortality. When it happens directly to someone you love, it often forces you to focus on your own life/health much more intensely, that you’re perhaps only a heartbeat from death. (Of course, I’m relating this to my own experience and our society in general, people in war-torn countries will understandably have a vastly different perspective on this.)
For me, the impact death has had on me was influenced to a large degree by my age and my relationship with that person.
