They're going to get a certificate? I've only gotten results orally, not like a piece of paper I can frame.
Or maybe "certificate" is a figure of speech, like a "clean bill of health"?
It does seem like a certificate only lasts as long as a condom.
Yes, after its been in your wallet for years its barely legible, no real use at all.
I would find it deeply unnerving if I were about to have sex with someone who pulled out a certificate. "Look! No diseasessss," I imagine they'd hiss.
