The most accurate way we have to express "always" would be to say once every second.
So there are 60 seconds in a single minute, and 60 minutes in each hour, and 24 hours in each day. That means that a non-diabetic body is checking and adjusting blood sugars and insulin levels more than 86,400 times every day.
It's no wonder we have such a difficult time trying to manage this on 10-12 tests per day!!
