The method of loci means mentally placing each item to remember somewhere familiar, like your home, then walking through it. In a 2017 study, beginners who trained for six weeks more than doubled how many words they could recall, and their brains began working like those of memory champions. Your kitchen can hold your shopping list.

Muscle responds to training at any age. Getting up from a chair without using your hands is already an exercise.
