Yeah, I would think that folks closer to retirement and closer to collecting social security anyways are less likely to be reviewed when there is such a backlog..

I'm 32 and started collecting social security when I was 18 and haven't been reviewed ever.. when I was 18-31 I was collecting SSI, which has now been turned into survivors SSDI.. I was diagnosed with 'schizaffective' (or bipolar with slight schizo tendencies) which was labeled 'improvement not likely' (7 year window).. hopefully cases with 'improvement not likely' attached to them have the same fortune as mature folks in terms of likelihood of CDR.. the backlog issue was real, but I unfortunately heard that the government passed something, like a sum of money to SSA recently to start cutting that backlog (hopefully this is not the case)
