THREE RIDDLES

1. What do watermelons and professional tennis players have in common?

2. What can you give to someone who will then have to give it to someone else?

3. Millions of people in the United States had died of it before 1951 - but none since. What is it?

Answers:

1. They're both seeded. 

2. The floor (as in Congress) 

3. Old age - Old age was officially deleted as a cause of death in 1951. All state and federal agencies were ordered to adopt a standard list of 130 contributing and underlying causes of death - no more "old age."
