Healthier
-------------------------
Two old guys were sitting in the park, talking, when the   
subject turned to getting older. 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 was able to get it up in  bed, but my wife is   
healthier than ever!" 
"Healthier? How is that?" his  buddy wondered. 
"Well, years ago, when we were younger, almost every night   
before bed she'd get these terrible headaches." he answered. 
"Now that we're  older, she hasn't had a headache in years."
