Yeah, getting old sucks. OTOH, the alternative sucks worse. But definitely not for sissies.
-24.5C here this morning, close to -30 next week. So far, I am still keeping RH under control in spite of it. The lung room is now at ~25%. The humidifier might have to go back in the 'drobe next week.
I am with you on the diabetes page, I have been on strict keto for a couple years to keep a lid on it. Low carb diet definitely limits options. It sure reveals just how much most normal diets are focussed on carbs, as well as how much sugar there is out there. OTOH, I expect my next A1C to be in the normal range or close to it, so the diet works.
Good luck with the diet and the grows.
