It depends what your body is familiar with. Our bodies adapt pretty well. If your body is used to values in the teens, 7 or 8 could feel hypo. My partner, who does not have diabetes, tests occasionally. I have never seen a value from him higher than 5.2 and, after a cycle ride, he has been in the high 3s. He does not experience hypo symptoms. And nor should he as these values are normal.
True. I went through a honeymoon phase in 2019 of BSG around 4-6's (somehow) and once I drank a bottle of wine, tested and it was 4 but didn't feel any different. Like you mentioned, I think it is based on where you normally sit blood sugar wise and what your body is used to.
