Today, we take the survey by the throat:

What do you do to keep yourself in voice for karaoke?
• Practice
• Drink milk when I sing
• Get plenty of sleep
• Exercise
• That's a bit much...

For such a big event it makes sense to go out of the way to NOT get sick. I even carry a small amount of all type of medication if I go on vacation even though I almost never get sick. The tiny waste in time it takes to pack it is worth not having a trip ruined if I get sick. It's actually helped in the past...when people I'm with get sick not me and they don't have medicine since unlike me they aren't paranoid.

There's being paranoid, and then there's being properly prepared. You'll do swimmingly once the Apocalypse rains down on earth, The_Vault_Dweller (as your name implies).

For the poll... Sleep. It'd be great if I can squeak in maybe 8 hours of proper sleep...
