Ahhh, we live in A Brave New World, do we not?
Many people proffer reasons for those things which they do. We want to be intelligent, deliberate creatures. Much like intenet postings can come back to bite one in 10, 20 or 30 years, so too, I believe, can the sytematic extraction and canning of our (or, worse yet, our children's) blood, dna, placenta, umbilical cord, etc.
Some of us misplace our faith in humankind...others are simply way too trusting. I don't like the fact that my wherabouts, travel habits, spending habits, etc. are constantly being monitored and evaluated through my speed pass and credit card purchases. It's a fact of life in the 21st century (I use cash when I want to remain incognito and under the radar). I certainly do not want my blood and dna siphoned out of me, and "safeguarded and stored" in some remote corner of the Earth (nor on Wall Street). It's a Brave New World.
