Oh boy, do I have some bad news for Bear Grylls. Apparently, drinking pee actually dehydrates rather than hydrates you due to urine's high sodium level. Poor Bear!
So now we all know we don't need to drink pee, it's time to download dSurvival, the app equivalent of a Swiss Army Knife. Starting with the essentials: flashlight and compass/GPS, dSurvival also boasts an SOS kit and distress signal, seismometer and teslameter for measuring magnetic fields (presumably for if you find yourself on the island from TV series Lost). dSurvival drops from Rp9 500.00 to FREE.
