When you use a hammer drill to drill on the wall or on concrete, do you need to wear goggles for safety? Is it necessary?
I think it's more like their her safety net. Her father gave them to her, saying that it would help control her powers. She believed it and it had been shown as long as she believes it, she could do it. She trusted her father so she trusted it would help.
I would not go modifying smoke detectors, and I have never seen a 'plug and play' add-on for a louder siren Smoke detectors as they are have a pretty ear-piercing sound. Maybe add another detector to the system right in your bedroom?
Not so much as health but for safety reasons. Electric blankets can cause burns. Our body temperature rises as we sleep and if you lay with an electric blanket you can get sometimes a sever burn. It happen to my mom, she had gotten a 2 nd degree burn from sleeping with one.
