I've long been fascinated by people who've experienced strokes or brain trauma. My grandfather experienced his first stroke when I was quite young, and I watched his efforts to recover physical movement, memory, and control of thought processes. He tended to repeat himself, as he had to when first working on recovery. That repetition served to re-build his memories.

For that reason, I'm generally opposed to Living Wills that work in favor of pulling the plug too early, or even those that favor sedating the patient into an early death. I've made my wishes known to my husband and children, and will be filling out the Right to Life website's alternative to Living Wills.
