How old was George Washington when he died?

Washington first took a leading role in the growing colonial resistance in 1769, when he introduced a proposal drafted by his friend George Mason which called for Virginia to boycott imported English goods until the Townshend Acts were repealed. Parliament repealed the Acts in 1770. Washington regarded the passage of the Intolerable Acts in 1774 as "an Invasion of our Rights and Priviledges". In July 1774, he chaired the meeting at which the Fairfax Resolves were adopted, which called for, among other things, the convening of a Continental Congress. In August, he attended the First Virginia Convention, where he was selected as a delegate to the First Continental Congress.
