MJ Broke His Arm?

correct if I am wrong but I don't think a surgical mask can protect you from pollution and/or viruses , don't you need a n95 mask for such things?

As for wikipedia you wear a surgical mask if you don't want other people to get any sickness that you have , it is not the other way around.


from wikipedia: A surgical mask is intended to be worn by health professionals during surgery and at other times to catch the bacteria shed in liquid droplets and aerosols from the wearer's mouth and nose. Outside health care facilities, simple, inexpensive masks of similar appearance are commonly worn in heavily populated centres in East Asia to help prevent spreading the common cold. In Japan, it is common to wear a face mask while sick to avoid infecting others in public settings
 
I don´t know if Michaels mask gave that much protection for him but I´m sure thats the reason why he wore it.
He had to avoid infections because his lungs wasn´t good.
