O2

Jogging and trees Sun.Star Network Online: "WHAT'S the common factor between jogging and trees? Oxygen!

When you jog, you need more oxygen and trees supply it. Jogging, which is good for your physical and mental health, also leads to a significant increase in your oxygen consumption and heart rate, especially if you are jogging uphill. So trees are actually more valuable than you think."
