If you fall asleep with your heavy head on your arm, you might not have the dexterity, or control of your hand, to hit the OFF button on the alarm clock in the morning.

Very small children do well with mittens, because their dexterity, or skill in using their hands, isn’t as developed as in older kids and adults, who wear gloves to separate their fingers. Dexterity helps fingers and hands to coordinate for completing fine tasks like writing, sewing, and playing string instruments. "Mental dexterity" means a sharpness of mind, or skill in thinking creatively and understanding and expressing something quickly and easily.
