Asking about upper age limits to work can shake the employer up

[PatrickR720159]

We still smell the sign of age discrimination when it comes to applying for work.  And when employers know they only want young people, they don't want to admit it.  So asking about an upper age limit is a good way to force them to tell the truth.  But some will even come up with a lie right there because they fear if they say what the maximum age limit is to work there and it sounds like if the maximum age limit to work there is in the upper 20s, what they are scared of is that we might create a petition to get the CEO of that company to scrap the upper age limit.  I would sign any petition to scrap upper age limits in the world of work.  Because upper age limits in the workforce are all stupid.

That depends on the job and the specifics of the job that are NOT age related:

From various headings at this site:  https://www.eeoc.gov/prohibited-employment-policiespractices 

The laws enforced by EEOC prohibit an employer from using neutral employment policies and practices that have a disproportionately negative impact on applicants or employees age 40 or older, if the policies or practices at issue are not based on a reasonable factor other than age.

. . . . the employer may not use a test that excludes applicants age 40 or older if the test is not based on a reasonable factor other than age.

If an employer requires employees to take a test before making decisions about assignments or promotions, the test may not exclude people of a particular race, color, religion, sex (including gender identity, sexual orientation, and pregnancy), or national origin, or individuals with disabilities, unless the employer can show that the test is necessary and related to the job. In addition, the employer may not use a test that excludes employees age 40 or older if the test is not based on a reasonable factor other than age.

In some situations, an employer may be allowed to set age limits for participation in an apprenticeship program.
