A raindrop could fall in the eye of an old man picking dandelions from his garden. He could fall backwards and trip on the hoe he forgot to pick up (again). His leg could break in those few seconds. He would have to go the hospital by car with his nervous wife who won’t stop crying, surely.
They would take him back into a room and check his injury. They could find a mass in his leg that is concerning, something he probably had dismissed as a part of his arthritis. They would take a biopsy.
A week later, because of that single second when a raindrop startled a feeble old man, he could receive a call from his oncologist. That old man would be reassured that they caught his leukemia early and it would unlikely that these are the last of his days.
