Your best bet is a basement or the innermost room of a solid building. Think of it as the world’s worst game of hide-and-seek, where the seeker is glowing and gives you radiation sickness. Avoid windows, external walls, and anything that looks flimsy—like that garden shed you’ve been meaning to fix for three years.
If you live in a terraced house or a block of flats, go to the central corridor or stairwell. And if you’re in a car at the time? Abandon it faster than a boyfriend who forgets your birthday. Cars offer about as much protection as a paper umbrella in a hurricane.
What About a Bunker?
Most of us don’t have a secret government bunker under the garden shed—sorry to disappoint the conspiracy theorists. But if you’re lucky enough to have a cellar or a storm shelter, that’s your VIP lounge. Otherwise, the inner hallway, a bathroom (with no windows), or a large cupboard will do. Bathrooms are surprisingly good because they have water and a place to sit, which is a luxury in these dark times.
