Health or Wealth?

Ninety-year-old man: "Yes! After all these years, I've finally kicked the habit. I'm a free man. From now on, no more sex. I'm going to be celibate for the rest of my life!"

Friend: "Wow! What happened? Are you concerned about your declining health?"

Ninety-year-old: "No, I'm concerned about my declining wealth. That darn Viagra was so expensive, I couldn't afford cigarettes."
