Left hand writing and right hand writing

Writing with your non-habitual hand is an easy, interesting way to trigger the brain to behave differently.

This is old, old information. I'd use it in writing groups: we'd all write with our left hands (or right, for lefties) for 10 minutes. Often, people were astonished by the words they wrote: apparently an alien had done the writing. Liberating, it was.

Well, I hadn't done that for years. But recently, as part of the save-my-brain-campaign, I've started writing shopping lists and such with my left hand.

The content doesn't surprise me. It's still the same old shopping list:
bread
yoghurt
coffee
oranges
iPhone
character dancing shoes
and so forth.

The surprise is in the writing style. Much more legible than my normal writing, which has been out of control for decades. More rounded and childlike, less pointy and mean. A little similar to my father's writing.

If the alien takes over, what will my shopping lists look like then?
