Sorry–hope this hasn’t been addressed before (but if it has I can’t find it…) I’m in the middle of a cold and as I lie awake at night I can’t help but wonder----where does all this stuff come from??? Where is it stored and what purpose does it serve? How do I stop it?-and should I try to??) ? If it really serves a useful purpose (i.e. flushing out germs and other undesirables) then fine, but has anyone really proved that this outpouring is really worth the aggravation it brings???
