Can we make a quick escape from quicksand?  Is it really good for us to lick our wounds? Why do we have different accents? We tackle these questions on this Week's Ask the Naked Scientists, as well as find out why having the flu gives us the shivers, whether its possible to eat your way to having a baby boy, and if fizzy drinks make for a fun flight!
