Two years ago this November, when my older sister was 19, she came down with something. She spent a lot of time coughing up mucus (and later, blood) of various color, size, and consistency, as well as having bloody noses and ear infections, and generally having a terrible time of life. This was after she went to live with my dad, so I only saw her two days a week when the rest of the sibs were there as well, so I wasn't there to nag her to take care of herself like I generally do. Anyway, she didn't do anything about it because she's always been prone to bloody noses and colds and whatnot. I think she attributed it to the crappy diet she had after she left Mom; frosting for breakfast and that kind of thing. It was a bit stupid of her because she'd never been this bad before, but people will be stupid.
Finally, finally, just before freaking Christmas, she went in to see a doctor. Turns out she had pneumonia. The doctor swore that if she had presented herself just one day later, just one day worse, she would have been an inpatient with a bed and an IV drip in her nose. As it was, she got the world's largest pills of whatever it was (600mg per pill, two pills at a time, three times a day) along with I think some other treatments and spent Christmas in bed, her ears draining some seriously nasty business. It was a miserable fucking holiday for that child.
For Maude's sake, people, if you're sick, get yourselves checked out! Stop putting it off! Go! Now! Pick up the damn phone and make an appointment before you !$%$%&*# kill yourselves.
Raise up the torch and light the way.
