How old is too old to serve in Congress?

Senate Minority Leader Mitch McConnell and Senator Dianne Feinstein, both in their 80s and 90s, recently faced cognitive challenges, sparking a debate about age limits in Congress.

Its a tough 15 seconds to watch - 81-year-old Senate Minority Leader Mitch McConnell clearly struggling.

 McConnell's 90-year-old senate colleague Dianne Feinstein had a similar cognitive breakdown just a few weeks ago when an aide was compelled to instruct her to simply "vote aye" after the six-term Democrat launched into a stumbling speech. 

 Bottom line - how old is too old to serve in the United States Congress?
