Apparently lots of diabetics reuse lancets (thread on another HN story a day or two ago). But I can't imagine anyone sharing used lancets (or needles... except for desperate addicts).
Would be interesting to see the rate of Alzheimer's among addicts and former addicts. But I imagine the sets "IV drug users who share needles" and "people who live to be old enough to be at risk for dementia" don't really intersect in any meaningful way.
Can confirm, am diabetic T1. Lancets don’t get changed much on my meter, but if anybody is curious I have a whole separate glucose meter/lancer device and brand new lancets to use.
