The National Center for Biotechnology Information (NCBI) says many pathogens are not caused only by genetic alterations but as a result of the environment reprogramming our DNA. This re programming can have positive or negative side effects. Our bodies are trying to adapt to a changing environment. Deleterious epigenetic programming is epigenetic changes that are not beneficial to us like those that cause chronic illnesses. This reminds me of my days as a programmer. Bad data can sometimes be caught and raise an error but other times it causes the program to crash (death). Programs try to deal with what ever is thrown at them but sometimes they can’t handle it.
