TMI or whatever but one time I was given the antibiotic for something and it didn't have a "refrigerate" sticker on it and no one told me to. By the 6th day it was very chalky and yellow so my mom poured it out. I am now antibiotic-resistant to that specific antibiotic. (It's called flu-something)
You’ve just been lucky because what happens is that if you don’t kill all the bacteria, some still remain, even if it’s just a few of them, they will adapt and evolve right in your body to be resistant to that antibiotic, it will then infect other people and that antibiotic won’t be able to kill it anymore and scientists will have to develop a new antibiotic which is really difficult. So it puts the whole population at risk
