Presidential age upper limit

[BrianSoddingBoru4]

The Constitution requires a President to be a minimum of 35 years old, yet has no maximum age.

Could Congress pass legislation to effect  a maximum age without having to pass all the hurdles of an amendment? Would it have to be another amendment -- and if so, what do y'all think of its likelihood of passage? How would you urge your congresscritters to vote?

As much as I know about it (and I'm no expert), placing a restriction on the age of a president would have to be done via an amendment. In theory, it could be done without the congresspersons being involved at all.

I don't fancy the chances.
