title. I feel like you always hear stuff to the liking of "high stress leads to poor health," but I am kind of wondering exactly why this occurs.

For instance, it's said that stress can cause:

• Aches and pains.
• Chest pain or a feeling like your heart is racing.
• Exhaustion or trouble sleeping.
• Headaches, dizziness or shaking.
• High blood pressure.
• Muscle tension or jaw clenching.
• Stomach or digestive problems.
• Trouble having sex.
• Weak immune system.

Imagine, hypothetically, that I were to have a high stress life, but still had good sleep, low blood pressure, and a slow heart rate, while also staying away from unhealthy habits like drinking or addiction.

Would my health still be worse than a person who lives an equivalent, but less stressful life than me?
