Is it correct that there is damage to the mitochondria as a result of serving in the Secret Space Program (Mercenary Army Program)?

This is a false notion. What people have observed and perceive intuitively in survivors of the Secret Space Program is the perturbation caused by the extreme stress they endure as a part of the program. This causes many adverse health effects no different from anyone subjected to chronic stress and repeated trauma. There are many psychological and physical markers that can be detected depending on the resilience and how long they were in the program and the severity of the experiences they had during their participation. If they wash out early they are lucky and are spared the worst of the training. Those who are stronger will carry forward longer and then things become worse and worse. Eventually what pushes them over the edge is so severe it can in fact be a shattering experience for the soul and that can have very severe long-term consequences, leaving the person in very poor psychological condition to maintain a productive life—let alone ongoing happiness at a decent level.
