I love big pharmaceutical advertising. Why take a pill daily when you can take a pill once a month?
I'll tell you why. Taking a pill daily forms a habit. Habits are easy. Taking a pill once a month requires that you think, mark it on your calendar, wear one of those stupid strings around your finger to remind you.
Give me a daily pill.
Better yet, let me improve my diet and start exercising. Perhaps I won't need drugs, then.
[But perhaps I will.]
