IMHO one's decline is a progression of self-abuse over many years. I have seen this many times by observing the health habits of friends and most recently my gentleman friend of 20-years (R.I.P.) through the addictions of cigarettes, alcohol, and the wrong food.
I have inherited some crappy genes ~ low intelligence, alzheimers, parkinsons, diabetes, etc. As a result, I'm trying my very best to live the most healthy lifestyle within my control to overrule those bad genes. So far, it's working ~ at age 73 I don't need any prescription drugs and I feel great
