I just started reading "The Stress of life" by Hans Selye. He is a pioneer in the research on stress and its effects. The main point is that we cannot live without a certain level of stress

He also confirmed one of my beliefs: That we were made to move. He writes "As we have so often said, living beings are constructed for work and if they have no outlet for their pent-up energy, they must make extreme efforts at adaptation... "

So choose the good stress over the bad. This is one more way to show you that physical activity is vital to your health.
