Many regions of the brain literally shrink in size as adults grow older. The hippocampus, which is associated with memory and spatial tasks, is known to lose about 1-2% of its volume per year. As a result, memory eventually begins to suffer. But hippocampus shrinkage isn’t necessarily inevitable.

Aerobic exercise is the elixir of youth for hippocampi.
