> Why don’t they have an age limit on the president (or any elected office)?
Because age is no indication of fitness for any kind of activity or role. It sure would be nice, if persons with high responsibilities would periodically undergo a fitness test. I'd think the founding fathers saw the election process as such fitness test and the electoral college as the judge of fitness of the presidential candidate.

This is a generalization that overlooks the nuanced reality of human aging. Physical and cognitive functions become more pronounced in advanced age, such as above 70 or 80. Sure, age alone does not universally determine fitness for activities or roles, but it is a very important factor to consider. I am fine with fitness tests.
