Don't take genes too seriously. If you search for Dr. Bruce Lipton's lectures, you'll see that the environment informs the DNA, so it's not all DNA-related. I mean even if you google alzheimer and identical twins, you find studies which prove that people with the exact same DNA may have or may not have alzheimer:
Even identical twins, who share all their genes, differ in their vulnerability. The study found only a 45 percent concordance rate for identical male pairs. This means that of all pairs where one twin has Alzheimer's, 55 percent of the healthy twins either will never get the disease or will develop it later in life.

Now 55% difference with people having the exact same DNA isn't very "promising" in terms of predicting what the DNA does.
So don't worry too much about it. The biggest contributing factor is the mental attitude you carry. If you are engaged in life, you have some purpose, some activity that you love, then you have nothing to fear.
Geriatric diseases are for those who have entered the psychology of the situation that they are less active and they are just (sublimely) waiting to die, and thus their body triggers various conditions to confirm their sublime expectation.
For example, new pensioners are at the highest risk of dying because they are like "I won't be working anymore, what am I going to do now? I'll be sitting around just waiting to die" on a subconscious level - and lots of times that's precisely what happens near the time they get the pension. They feel "de-activated" when retired and this feeling is then translated to the body which "retires" on its own.
So the feelings, intentions and the mental attitude are running the show in ways that chemicals and genes don't. The biggest medical "anomaly" that highlights this, is the existence of multiple personality disorder. When an individual wears a different personality, they get a whole set of different pathological symptoms. Then they switch personality and they switch symptoms. In one personality they may be diabetic while in another they are ok. In one personality they may be blind or short-sighted and in another they are ok. Things like that vary depending the "software" that the mind is running at each given point. But for most people running just 1 software for their personality, they don't realize how that dominates what their body does.
I agree, and I know that we are still in the very early stages as far as understanding genetic science. The most helpful info for me was understanding the MTHFR gene, which has a pretty actionable fix that seems to have produced results for me. As far as the odds of getting Alzheimer's, I take the genetic predictions with a grain of salt. Thanks for the resource, I'll have to look more into Dr. Lipton!
He is a molecular biologist. He used single-cell organisms from which he extracted the DNA from the cell and realized that the cell operated normally. And then he asked, if DNA was controlling behavior, why is this cell working normally (except reproduction of course). So he quickly realized that DNA doesn't control behavior but it's the other way around. And then he built up from there, studying anomalies where DNA should do this and that (and didn't) or where the environment or person's attitude was more of a causal factor.
Btw, I've experimented myself with the electrode neural stimulation in the past and one thing I noticed was extreme reaction to stimuli. Say a mosquito flies near your ear and then you react quicker and more violently. Have you noticed something similar? (It's possible I've activated some weird neural cluster with the points I was touching the electrodes)
I haven't noticed any reactions like that, but I have not delved very far outside of the more mainstream placements. I am working right now to develop unbiased tests for these placements and I hope to test some of the other placements soon.
