Work in a kindergarten or fly international during Christmas.
Snot every where is not fun
I got Flu Type B on the way back from LA this year ... I still can't figure out why I was shivering on the plane all the way home. Thank goodness I made it through the body heat sensors at Narita or I would have been sitting in quarantine
Nope, don't get the flu shots ... however I've only got the flu 2x in 38 years both times in Japan
