Once upon a time there was a chef.
And every day he would go out in search of natural ingredients for his recipes.
Until one day he injured his thumb while preparing some ingredients.
And because of this it took him twice as long to prep and cook his dishes.
And because of this he started having to use his non-dominant hand to help prep and cook.
Until finally he had used it enough that he could double his effort.
And ever since that day he’s been simultaneously prepping and cooking two recipes, one with each hand.
