Stress also is a major cause for sickness. When a person is stressed the body can't heal itself as well. The sole fact that people have to worry that they have enough money in case something happens to them, or that if they have no money and something happens is enough to make a person not be able to heal themselves when they may have been able to under different circumstance.
