Am I a viable human being? For my continued life I am dependent on the medical/pharmaceutical industry that is far beyond my capability to replace on my own. Most obviously, I, as a diabetic, am dependent on a continual supply of insulin that I cannot produce myself, either in my pancreas or through other means at my disposal. I don't know how long the rising blood sugar would take to kill me, but probably weeks, not years. Similarly, my high blood pressure without my meds would do me in. So, since I cannot fully take care of myself but am absolutely dependent on others to be viable, am I a viable human? If that viability is the crucial determinate of personhood and human rights, have I lost those rights?
