Avoid Depression in Old Age by Being Fit in Middle Age
Being physically fit in middle age may prevent 2 things: developing depression as a senior, and dying from heart disease if you do happen to become depressed.
Researchers looked at 18,000 Medicare individuals and found that those who were the most fit were 16% less likely to develop depression. The fittest were also 56% less likely to die from heart disease if they developed depression, and 61% less likely to die from heart disease if they remained depression-free.
