Sorry for your loss.
I'm reading various Facebook posts about life in one's 70's. There are hard truths that we all experience as we get older. One of those is the loss of family and friends. The circle of the living tends to get smaller. Yet, in a very real sense, we are the lucky ones. Lucky that we'll all die because we all lived.
Take a look...

We are all going to die, and that makes us the lucky ones. Most people are never going to die because they are never going to be born. The potential people who could have been here in my place, but who will in fact never see the light of day, outnumber the grains of sand of Arabia. Certainly, those unborn ghosts include greater poets than Keats, scientists greater than Newton. We know this because the set of possible people allowed by our DNA so massively exceeds the set of actual people. In the teeth of these stupefying odds, it is you and I, in our ordinariness, that are here. We privileged few, who won the lottery of birth against all odds, how dare we whine at our inevitable return to that prior state from which the vast majority have never stirred?
