I have found in my study that allowing the calendar to turn, at no drive, no cost, and no exposure in a store has approximately the same effect. However, not knowing how long that *same cold under the same conditions* at another time would have lasted if I had driven to the store, purchased and consumed the product does admittedly leave a hole in my study.

Color me skeptical, but them I'm pretty much that way in today's marketplace.
