I was an asthmatic child. Still am as an adult but I sort of out grew it in my teens. It still pops up when Im sick, or when air quality dips, or if I get allergies, or its there but Im used to it and it’s not as bad as when I was young.
As a kid though oh man I would frequently come down with colds and frequently have a clogged nose. It was not uncommon for me to breath through one nostril for a day, then it might shift later that evening and no amount of blowing or picking would save it. Then of course when I was sick which again was frequent I would be a mouth breather.
I still loudly sneeze through my mouth as an adult, not because I want to make a scene but because sneezing through my nose would hurt and lead to two snot trails flowing down my face.
Its funny now that I think about it I usually dont carry tissues with me but as a kid I always had a pack in my pocket because snot was an inevitability.
