Long-term physical activity can help to reduce your heart rate through its response to exercise: an increased stroke volume leads to a lower stress response and therefore less cortisol is produced, allowing for a more homeostatic environment for the lymphatic system.
Choosing to not use tobacco is the start to leadership and control over how you want to live the rest of your life. You stay looking young, healthy, and you're not at high risk for developing cancer in your heart or lungs. Many tobacco users age quicker, lose their voice, develop cancer, have severe kidney problems, and can even result in death.
That's my answer :) hope it works!
