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.
Martha Wayles Skelton Jefferson (October 19, 1748 O.S. â September 6, 1782) was Thomas Jefferson's wife. She was born at The Forest, the plantation home of her father John Wayles. Her mother, Martha Eppes Wayles (1721-1748), died just a week after her daughter was born. Martha Wayles was married first to Bathurst Skelton on November 20, 1766. Their son, John, was born the following year, on November 7, 1767. Bathurst died on September 30, 1768. There are no known portraits of Martha Wayles Jefferson, and descriptions of her appearance are scant.
