Update: The jump was a success. Here's a snapshot:
Bush is only the fifth president to be a nonagenarian -- but Jimmy Carter, born only four months after Bush, will hit the milestone later this year. The longest-living presidents, by number of days lived:
- Gerald Ford: 34,133 days
- Ronald Reagan: 34,088 days
- John Adams: 33,119 days
- Herbert Hoover: 32,943 days
- George H. W. Bush: 32,872 days
- Jimmy Carter: 32,761 days
- Harry S. Truman: 32,373 days
- James Madison: 31,150 days
- Thomas Jefferson: 30,397 days
- Richard Nixon: 29,688 days
Or if you prefer, here's the whole set. Those in green are still adding days to their tallies.
Bush, as far as we know, is the only one to go skydiving as a hobby, much less once he passed the 90-year mark.
