No, not all hand flapping is automatically a sign of autism. It can be. I think there are a lot of kids who are diagnosed with ASD (autism spectrum disorders). Most of that has to do with the spectrum being broadened in recent years. Some of the kids included on the spectrum barely have delays!
Thomas Jefferson's Death. After being president, Jefferson retired to Monticello. He sold his book collection to be the base of the Library of Congress. At 76 years old, he played a major role in the founding of Virginia University. He died of unknown causes on July 4, 1826, just hours before his friend, John Adams. Since he was 83 years old, it is assumed he died of natural causes.
