Big Brother can make sure you take your medication?
For the mentally ill, elderly or other folks who can't track when they take required medication this can be a huge winner.
Do I want Pfizer tracking what meds I'm taking in real time? Sure...I trust those guys. I realize they've paid the largest fines for fraud imposed the the US Federal government in our countries history (over $2 billion to date) but they've turned over a new leaf and are honest now. I promise.
