Safety adviser Murali Krishnan points out that walking and using your phone both demand large amounts of cognitive effort.
Blind spots aren't inevitable in all vehicles, argues user Kristen Rush.
By adjusting your mirrors so that you barely see the edges of your own car, you can effectively eliminate the blind spots on the sides of the vehicle. The rear-view mirror should be able to locate any car behind yours. It's worth the few seconds it takes to adjust these when you get in the driver's seat.
There's a connection between being wet and getting cold, and vice versa for heat, says engineer Lia Lavoie.
Lavoie also points out that your body uses a great deal of energy to convert matter from one state to another.
Naman Mitruka explains how to perform the Heimlich on yourself:
Ideally, you'll be able to turn off the source of the electricity in this kind of situation, Alex Elderfield explains. But if that's not possible, you can help the person (without getting electrocuted yourself) by breaking the circuit. The simplest way to do that is to find a long hard object, like a stick, and give the person a firm whack.
Survivalists have a shorthand for knowing their limits, Ruchin Agarwal says.
Pulling out an object that has been lodged in your body will increase the rate of blood loss, Thomas Mei explains. Instead, try to cover the wound and do anything you can to stop the bleeding until you find a medical professional.
Instead of using mace or a weapon, an extremely bright flashlight can also effectively ward off a mugger, user Sanket Shah claims.
If a line falls near you, keep your feet together and jump or shuffle away. If you take normal steps, you're at risk of conducting electricity in your body since the current can flow through both legs separately.
