Hans Selye proposed the idea, that a human or another biological individual possesses the reserve of the ability of adaptation. This reserve can be exhausted either during long life gradually for overcoming the great number of inconsiderable stresses, or rapidly - for the withstanding of little number of significant stress. So, if an individual pass through the strong stress in the begining of its life, it becomes less resistant for the following impacts of stressors. Can we talk about the reserve of adaptation, that 'serves for saving' several consecutive generations? For example, can we expected, that because the residents of Fukusima & Chornobil were sensibilized by radiation exposure, their childs & grandchilds will be more vulnerable to various stressors as compare with the other groups of population (those, which weren't radiosensibilized)?
