These days the incidence of various degenerative diseases of mind are constantly on the increase. The main reason behind the high incidence of mental decline diseases like Alzheimer's disease, Parkinson's disease, dementia etc. is the highly stressed environment in which we line. Also the food that we eat these days is lacking in so many essential nutrients which are vital for healthy brain and body.
Although, we do not feel the symptoms of mental and bodily decline during our young age due to effective repair and regeneration mechanism of the mind and body, overtime both our brain and body start to weaken due to the inefficiency of our internal repair and regeneration mechanism to protect the organs of our body from various kinds of stress both internal and external.
