Do not regret growing older. It is a privilege denied to many.

Robert, 85, married Susan, a lovely 25 year old. Since her husband is so old, Susan decides that after their wedding she and Robert should have separate bedrooms, because she is concerned that her new but aged  husband may over-exert himself if they spend the entire night together.
  After the wedding festivities Susan prepares herself for bed and the expected knock on the door.
  Sure enough the knock comes, the door opens and there is Robert, her 85 year old groom, ready for action.
  They unite as one... All goes well, Robert takes leave of his bride, and she prepares to go to sleep.
  After a few minutes, Susan hears another knock on her bedroom door, and it's Robert, Again he is ready for more 'action'.
Somewhat surprised, Susan consents for more coupling. When the newlyweds are done, Robert kisses his bride, bids her a fond good night and leaves.
She is set to go to sleep again but, aha you guessed it, Robert is back  again, rapping on the door and is as fresh as a 25 - year - old, ready for more 'action'. And, once more they enjoy each other.
  But as Robert gets set to leave again, his young bride says to him, 'I am thoroughly impressed that at your age you can perform so well and so  often. I have been with guys less than a third of your age who were only good once. You are truly a great lover, Robert.'
  Robert, somewhat embarrassed, turns to Susan and says: 'You mean I was here already?'

The moral of the story:
  Don't be afraid of getting old, Dementia has its advantages.
