Does age impact chances of getting approved?

I’m just curious if age affects your chances of getting approved for cpp disability? My husband is mid fifties, so he could start collecting a reduced cpp in a few years anyways . Does this make it more possible he may get approved? Or does it not impact it at all?

Under 50 is harder to get.
I don’t think older makes a difference.
He should fight for it and then his regular CPP won’t be reduced.
