I have a great-uncle who is in his 70s (brother of one of my grandmothers). About 2-3 years ago his wife died suddenly of inoperable cancer. From diagnosis to 6 feet under was about 2 months at the most, she was always healthy before that and she went in to the doctor because she was feeling tired for no clear reason. She was one of the nicest people you could ever hope to meet.
And he is as well. He has been a farmer all his life, also doing woodworking on the side in a small mill he has built on the family farm. He loves showing local kids how both the farm and the mill work; he has cut wood for the area for a long time and helped to build more than a couple houses.
After his first wife (to whom he had been married for almost 50 years) passed away, the family was shook up. But he deserved to be as happy as he always made everyone else; he eventually met up with a widowed woman his age who he had gone to primary school with so-many-years-ago. The two of them dated and eventually decided to marry; they both knew that they were getting old enough that time wasn't on their side anyways.
Then a few weeks ago that was confirmed for his second wife.
She was recently diagnosed with cancer as well. By the time a surgeon specializing in that part of the body was available the primary care doctor suggested instead it was time for a family meeting.
Really, if there is a god, why would that god decide to punish my great-uncle like this? He cares for his family and his community. He doesn't smoke or gamble. One of his adult children is involved with ministry work in a former 2nd-world country.
