10/22   Does flu shot prevent common cold?  I guess it probably doesn't, but
        I'm just checking.  I'm thinking about whether or not I should get a
        flu shot.  Thx.
        \_ Is this a joke?
                \_ Just in case it's not, "no, it won't help."
                   \_ Thanks.  I guess I won't get the shot then.
                      \_ well... it should at least prevent the flu.
