I agree entirely. I am not suicidal in the least; I love every minute of life. But I am at peace with my own impermanence, whether it's tomorrow or 20 years hence (when I'm 94). So I take all this earnest medical advice with a healthy grain of salt.

When a potentially terminal illness hits (such as cancer, a stroke, or a heart attack)--well, I'll then hope I am lucid enough to make a sane and sensible decision about pulling the plug. The thought of Chemotherapy appalls me. Besides, I have arranged for a composting burial, in accordance with my deepest Gaian values, so I want to be sure that the body I return to Gaia will be as nontoxic as possible.
