This statement is from the book, 'What your doctor doesn't know about nutritional medicine may be killing you', by Dr. Ray Strand.
He seems to me to be saying that people nowadays are 'dying of degenerative diseases' rather than of 'old age', whatever that means. What do you think he means by 'dying of old age', and how is it different from dying of degenerative diseases?
I am a student of mathematics and (perhaps clearly) have no medical background. This book was recommended to me by someone.
