well, for me, I almost died, failed my exams and probably smthn else I'm forgetting but idk my memory is weird.
uh I got a cold and instead of taking medicine for it like a sane person I said "no, it's just a cold, it's not a big deal" but the cold decided to BECOME a big deal and my heart rate slowed down, I kept vomiting and couldn't eat cause everything I ate just came back up, my blood pressure was low, it was horrible. I'm okay now tho, and I learned my lesson to always take medicine if you have a cold cause if you don't it can lead to your grave.
