When I was 8 years old we had a really hot summer (I lived in Oklahoma), and I walked home from school and I thought I was having a stroke. I was just dehydrated. Anyway, I started drinking water really fast. My brother walked over to me and said "Careful, you'll hydrate yourself."
Until about two months ago (I'm 19), I thought hydrating yourself meant killing yourself.
