clint was too old for this role
should have stuck to directing only.
shareWell a major thrust of the story is that he is an aging, supposedly retired ex-thief. So his advanced age is tied into the narrative. There's even a joke about a pacemaker.
At the time of release, Clint would've been 67. So that sounds about right to me for the character. He could've been a little younger and the story would've still worked, but 67 is fine.
