Aging

On the article How to Live to 100, I saw this list:

Lifestyle habits that age you most quickly
The culprits that will most quickly age you and negatively affect your health are:

1. Poor diet
2. Lack of exercise
3. Stress and worry
4. Exhaustion
5. Unhappiness
6. Lack of love
7. Toxic overload
8. Blockages and congestion of the transportation highways within our bodies.

Hmm, sets me thinking.
