Mechanism Behind Mind-body Connection Discovered

"The study reveals how stress makes people more susceptible to illness." Science Daily Article.
This is a datum to support my assertion that the hypothesis that the "Problem of Evil/Suffering is a Test" is demonstrably false.

Every cell contains a tiny clock called a telomere, which shortens each time the cell divides. Short telomeres are linked to a range of human diseases, including HIV, osteoporosis, heart disease and aging. Previous studies show that an enzyme within the cell, called telomerase, keeps immune cells young by preserving their telomere length and ability to continue dividing.

UCLA scientists found that the stress hormone cortisol suppresses immune cells' ability to activate their telomerase.

The study reveals how stress makes people more susceptible to illness.

If the problem of Evil/Suffering is a test then it is a test that degrades the performance of the participant resulting in a negative feedback loop where the participants ability to cope is degraded as the test proceeds. If we are to be judged on our ability to cope with hardships, and our ability to cope with hardships is demonstrably decreased over time under the influence, and no two people have the same hardships, then there can be no consistent standard to judge by. This is not consistent with sound testing methods.

If the participant can only think and make decisions with the biological material they have at hand, namely their brain, and their brain is susceptible to degradation as is the rest of the body, then the problem of Evil/Suffering as a test is not as much a test of spirit as it is a test of biological integrity.

If however the spirit is a separate entity and is not susceptible to degradation, then while this may be a hypothesis, it is not consistent with any known observations and is only supported by anecdote and writings, some of which are of unknown origin. However, the degradation of spirit during hardship over time has been observed so much that it has become an expected outcome of hardship. Notable exceptions to this outcome are not limited to Christians and should not be used as a datum to support the Christian view of "The problem of Evil/Suffering as a test". Therefore it is a dubious hypothesis, if it can be considered a hypothesis at all.
