Sure, some of the time it's easy.
Let's all recall the words of my mother's medical school instructor, "There's a bit of cancer in everyone's prostate".
(The context was a lab exercise in which medical students were supposed to find which of a set of slides of prostate tissue was cancerous. The reminder was necessary because many of the slides were cancerous, just not at levels high enough to be considered medically alarming.)
Predicting that a man will develop prostate cancer is basically the same thing as predicting that he'll experience old age.
