Doctor asks his elderly patient how he stays in such good shape

The man was happy and healthy when he went for his annual doctor's check up, confident that he would pass any test the doctor could give him with flying colors.

Mr Smith left his wife sitting in the waiting room for him while he went in to the doctor's office for his examination. The doctor did all the usual tests, and seemed to be quite pleased with the results.

"Mr. Smith, you’re in great shape," said the doctor afterward. But being such an elderly gentleman, the doctor was curious as to how he had remained so healthy, and he asked the patient "How do you do it?"

"Well," said Mr. Smith, proudly deciding to let the doctor in on his secrets, "I don’t drink, I don’t smoke, and the good Lord looks out for me. For weeks now, every time I go to the bathroom in the middle of the night, he turns the light on for me."

While most of this sounded good, the doctor was quite confused by Mr Smith's closing statement about the light.

Concerned, the doctor found Mrs. Smith in the waiting room and confided in her what her husband had said, wondering if she had perhaps noticed anything strange in his behavior of late that could point to any underlying issues he might have missed.

Despite the doctor's concerned look on his face, Mrs Smith began to laugh, as she suddenly realized what it was that had been going on in her kitchen recently.

"I don’t think that’s anything to worry about," she told the doctor. "And on the bright side, it does explain who’s been peeing in the fridge!"
