"Electrical fire smells like fish. Caught it before a fire even started."

"I once saw a post on Reddit about someone who had a weird red line going up their arm. Everyone told them to go to the ER, that it was an infection leading up to their heart. A couple of years later, my husband cut his elbow. Two days later, he started with a fever and when I looked at his arm, I saw the line and made him go right away (we were on vacation and he wanted to wait until we got home). 3 days in the hospital and a surgery later he was ok, but the nurse told us he could've lost his arm or died if he brushed it off like he tried to. So thank you to that reddit poster!"
