Questions about Palin's ability to take over as commander-in-chief, should something happen to McCain, have made McCain's age a legitimate concern. Politico digs into the data:

...for a man who has lived 72 years and 67 days (McCain’s age on Election Day this year), there is between a 14.2 and 15.1 percent chance of dying before Inauguration Day 2013, according to the Social Security Administration’s 2004 actuarial tables and the authoritative 2001 mortality statistics assembled by the National Association of Insurance Commissioners.

Going by the Social Security Administration’s tables, that’s nearly ten times the likelihood that a man aged 47 years and 92 days (Barack Obama’s age on Election Day this year) will die before Jan. 20, 2013.
