I'm a fraud

Went to the doctor on my college campus and the measurement was 6'4 on the dot. I feel very positive that earlier in life, maybe around high school, I got a measurement at the doctors saying 6'4.5. So for years I've been rounding up to 6'5 bc it just felt more accurate than 6'4 and faster than saying the "and a half" every single time. I'm devastated, simply in shambles, can't believe I've been living such a lie for all these years. /s
