Bear Grylls survival masterclass

When tasked with a practical matter, apart from your dad, there’s only one other person you’d ever need on speed dial; Bear Grylls. However, as you’re more likely to regularly need help to build a flat-pack wardrobe compared to jungle survival tips, we suggest you keep your old man top of your contact list, and commit this guide to memory.

How to stay hydrated in the Sahara…
“Avoid any temptation to strip off, and keep your clothes on. The sweat in the clothes will keep you cooler and they will protect you from the sun. Keep your shirt on your back, take off your underpants and wear them on your head. You might look a bit daft but you won’t die quite as fast. Remember the earth is 70 per cent H20, so there’s always some water to be found, even in the desert. You have to be resourceful, imaginative and think laterally. Any water you own needs to last. I once skinned a snake and peed inside it so to not waste the water in my urine. The next day when I opened that snake back up, the heat and the intestines made it taste ghastly, but I drank it.”

On Second Thoughts: Urine is 95 percent water and sterile but only when fresh.
