Rules of Thumb

Finding Shortcuts

A big thumbs-up to the person who came up with rules of thumb.

They don’t always work of course – the point is that they work, generally speaking.

The same is true of Proverbs. They give wise advice, but it doesn’t mean every single scenario will line up perfectly. No matter, I reckon it’s better to be generally good at a lot of things than super at 1 thing.

Finding My Own Rules

After eating the same

at the same

in the same

while doing the same exercise,

I can consider simple rules of thumb for me

Here’s How I Write My Rules:

1 piece of pizza = _ units of insulin

That way of stating the rule of thumb means it’s flexible for whatever quantity I eat

How much more insulin do I use in winter than in summer?

Maybe I say “1/5th more” – if my summer average changes, I can guess what my winter amount will then be.

How does exercise change what I inject?

Is it 1/2 of the usual dose, say if I’m exercising just after a meal?

The more general + flexible the rule is stated, the more useful it is.
