If the retirement age is decided because that is the age we are likely unable to work, what insanity makes anyone think a geriatric can run the US?
Age limit should be set at the age elected is 2 terms worth of years less than the retirement age. Ie, if the retirement age is 65 and a term is 4 years, last age to stand for election is 57.
I'm sick of old fogies that have no clue about present society imagining they can run our lives. It's disgusting, IMO.
