a dash of endorphins, a pinch of serotonin

You know, they have a patch for everything now -- smoking, birth control, estrogen, testosterone, all kinds of things.

I saw an online ad today that showed a woman wearing a patch and said "Imagine seeing more results in a week than you have in a lifetime of dieting."

But I read this, on first pass, as "a lifetime of dating."

What would a dating patch do, I wonder? What drug would it deliver, what unintended consequences would it prevent?
