Two old men were sitting in the park, talking, when the subject turned to getting older.
The first man said "Women have all the luck when it comes to getting older."
"What do you mean?" asked the second bloke
"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 mate wondered.
"Years ago, when we were younger, almost every night before bed she'd get these terrible headaches." he answered.
