This always baffles me. You can usually tell when a TV presenter has a cold because they have the giveaway stuffy voice. But how do they stop their nose running while they're on air?
Whenever I have a cold I feel like it's a constant flow of snot and I have to sit with a tissue practically attached to my face.
And I know they have good makeup artists, but they never look puffy or red eyed.
I know this sounds like a really stupid thing to be thinking about, but they must have a secret.
