I get a flu shot every year because I had the FLU once. I was about 25. Before I had the all-caps FLU, I couldn't understand how there could be a flu epidemic that killed many people, isn't it just a bad cold, a fever?

No. My whole family got it and couldn't get out of bed, I am kinda surprised none of us did die. It was a week of just laying in the living room together so I could nurse the baby and we managed to get enough to drink somehow and change the diapers, but barely. I really did feel like I would die. I do now understand how flu can kill someone. Like if I didn't need to keep the baby alive I probably would have gotten too dehydrated and died.
