O.K. Lets talk about this, @Seydlitz. My Doc comes from a family where EVERYONE had type 1 and (probably) someone died due to hypo. Hypo freaks her out. Hypo does NOT worry me as much as highs, so we battle over this a lot. My best friend comes from a family with 6 type 1 diabetics out of 8 kids. In these cases, its important to recognize that families may have generations of trauma, due to early death, that impacts their perception/paradigm of the illness.
You are touching on the issue of ‘variability.’ Now, this topic has caused huge fights on this site in the past. So, I want to exercise caution in bringing it up. I can run under 7 pretty easily. However, the innate variability that I believe is inherent to my system (partially due to lifestyle) may increase epilepsy complications beyond what is reasonable, so we have decided NOT to run me much below 7.
I take the position that everyone’s system has a certain amount of variability that is inherent. This differs between individuals and for individuals over time, for instance you will see variability decrease with age and activity level. Running under 7 is not ideal for everyone, for instance, if you have trouble recovering from lows - ie. super hypoglycemic unaware and your system is highly variable, than this may not be ideal. Depends on the individual.
