Roger's Wedding...

Roger , 85,  married Jenny, a lovely 25 year old .

Since her new husband is so old, Jenny decides that after their
wedding she and Roger 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 Jenny prepares herself for bed andthe
expected knock on the door. Sure enough the knock comes, the door
opens   and there is Roger, her 85 year old groom, ready for action.
They unite as   one.   All goes well, Roger takes leave of his bride,
and she prepares to go to   sleep.

After a few minutes, Jenny hears another knock on her bedroom door,
and   it's Roger,  Again he is ready for more 'action'. Somewhat
surprised,  Jenny   consents for more coupling. When the newly weds
are done, Roger kisses his bride, bids her a fond good night and
leaves.

She is  set to go to sleep again, but, aha, you guessed it - Roger 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 Roger 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, Roger.'

Roger,  somewhat embarrassed, turns to Jenny and says: 'You mean I was
here already?'

The moral  of the story:

Don't  be afraid of getting old, Alzheimer's has its advantages.

PS..  Have I sent this to you already?
