Is good advice Eternal.
I have had more tests in the last 6 months than I have had in the 36 years. An MRI for a hearing loss issue showed I had scarring on the brain from at least 2 "cerebrovascular accidents" in the past. Meaning I had "silent strokes." Now waiting for the results from a CT scan on the same thing.
Still don't know why my ear rings and am losing hearing,
but I do know now I have to be more careful of what I eat and get exercise. So yes, it has a positive influence. I would rather know than be dumb and happy.
