Barbed wire, still an essential tool in the livestock industry, is today a popular collector's item.
At three points in US history, six presidents (current or former) were alive at the same time. These points were: From March, 1861-January, 1862: Presidents Van Buren, Tyler, Fillmore, Pierce, Buchanan, and Lincoln were alive. January 1993-April 1994: Presidents Nixon, Ford, Carter, Reagan, Bush (the first) and Clinton were all around. January, 2001-June, 2004: Still living were Presidents Ford, Carter, Reagan, Bush (the first), Clinton, and Bush (the second). When either Trump or Clinton take office in January, 2017, he or she will join Carter, Bush I, Clinton, Bush II, and Obama as living presidents, making it a fourth time in history six presidents were alive.
The second oldest president, William Henry Harrison, died in office, as did the fifth oldest president, 64 year old Zachary Taylor. And the third oldest president, 65 year old James Buchanan, despite his stellar government resume, is generally rated in many surveys of presidential performance as coming in dead last. Only our fourth oldest president, George H.W. Bush, 64 years old at his inauguration, seems to have escaped any hints of age impairing his presidency.
