Sounds like good advice to me.

Joe Joe Joe the VP offered advice today on TV

"I would tell members of my family — and I have — I wouldn't go anywhere in confined places now," Biden said. "It's not that it's going to Mexico. It's you're in a confined aircraft. When one person sneezes, it goes all the way through the aircraft." Biden went on to say he wouldn't suggest that they ride the subway either.
Avoid all airline travel? Don't ride the subway?"

Does he know something we dont ?

I wander what would have happened if George Bush had said the same thing?
