Quick Joke

A man was very interested in his health and heard about a seminar on nutrition that a local Jr. College was putting on, so he signed-up for it.
When he showed-up, there were all kinds of people there: young, old, males, females, different ethinic groups, etc. He was trully amazed at how many people had taken such an interest in this particular topic.
The speaker got up and began to speak about different foods and what they contribute to our everyday health. After a few minutes, he posed a question to the audience.
"What is the one food that has worst, long-term effects on young people's overall health?"
Several people raised their hands, giving out answers. One lady stood-up and said "French Fries", another said "Oreos", and a gentleman said "Any Fast Food".
When is had appeared that he had got all the answers he was looking for, a hand went-up slowly from the back of the room. The speaker called on the hand and 95 year-old man with a cane stood-up. Barely able to stand on his own, the man belted out "I should know after all these years.... it's Wedding Cake!"
