Today, at 67, I’m a full on 5 but maybe I was near “normal” in my youth — I just don’t know… hmm

I’m 67 and discovered my Aphantasia two years ago reading that first NYTimes article. I’m a 5 on the scale (zero image, complete blank) and it feels like it’s always been this way. Problem is, I also have the autobiographical memory problem (medium-ish) so I don’t trust my perception of my past. Maybe I wasn’t aphantasic at all back in high school. I really have no way to be sure. Does anyone else harbor these same doubts about how long their Aphantasia has been with them?
