No one knows........: No one knows. It's partly aging, a large part genetics, sometimes diet, sometimes weight, sometimes lack of exercise, but often it's genetics and ? The key is: treat it. Do any lifestyle changes you need (weight, diet, exercise) and take meds if needed. Hypertension doesn't hurt until it's too late. Treat it, no matter what the cause.

We don't know: Honestly, we don't really know. We know how it happens, what hormones and organs are involved and we know why it's bad. But as to what is the causative factor that starts it...We don't know.
