A national debate is growing about the aging of the country's political figures. This comes as tributes continue for late Republican Senator Lindsey Graham, who passed away earlier this month at 71 years old. The current Congress is among the oldest in US history, a trend expected to accelerate, particularly in the Senate.

Many Americans consider this to be a problem. Senator Mitch McConnell, 84, has been absent from congressional votes since a June fall landed him in the hospital, where he contracted a mild case of pneumonia. Further details on this topic are available from CNN, which recently conducted a survey on the issue.
