Two old guys were sitting in the park, talking, when the subject of aging came up. The first guy said, "Women have all the luck when it comes to getting older." "What do you mean?" asked the second guy. "Well," replied the first. "I can barely remember the last time I got aroused in bed, but my wife is healthier than ever!" "Healthier? How is that?" his buddy wondered. "Years ago, when we were younger, she'd get these terrible headaches almost every night before bed," he answered. "Now that we're older, she hasn't had a headache in years!"
