Please choose the correct ending to complete the given sentence: Education and Communications: [header] How to make yourself smarter [title] Practice doing simple chores with the " wrong " hand. [step] Try brushing your teeth or eating your breakfast with your non-dominant hand. Routine behaviors are run by the brain's sub-cortex, which control automatic functions of the body.

Ending1: Trying to do chores with this dominant hand allows you to stay aware of what you are doing. [substeps] Get comfortable with this practice by doing some simple tasks like doing a puzzle and pulling up drawers; you can also copy the example that you are doing and do a table of a situation with the " right " hand. Ending2: The upside of this is that small tasks do not require a meal to be done. Doing one small task like brushing your teeth, changing your clothes or washing your car will get your brain flowing normally. Ending3: Some examples of simple " basic chores " include cleaning your room, taking a shower, or feeding your pets (or the kids). [substeps] You can try taking a shower or doing the dishes instead of making dinner--in this case, you won't need to restrain yourself. Ending4: [substeps] If you make a point of mixing up your routines, your brain will be forced to be active and alert. For any activity to help exercise your brain, it must be both novel and complex.
