You are in some desolated place, alone (how you got there, I do not know), and without shelters. You see no-one. No-one at all. You shouted out loud, thinking--wishing--that somebody would shout back in response. Company is always welcome in times of desertion, after all. To your frustration, however, nobody shouted back.
Since there are no landlines in the area (the area being an inhabited one), the only hope that you can see--the only hope that might save you--is your mobile phone. Hmm. perhaps you could call somebody? You worried that there might not be any cell site, but you still pursued on using it, since, as I have told, it is your last hope.
To your surprise (not to mention extreme horror), you find out that your mobile phone's out of battery energy!!! What luck, ain't it? You were the luckiest guy on earth, stuck in some lonely universe with no means of contacting outside forces.
You might say that no, why on earth will you be alone in a place like that? Well, Who knows what might happen? You could be on a plane then the plane landed or things like that. The point is, it is not impossible to have yourself stranded in such a place. When this happens, you should be ready, just like a boy scout or a girl scout. It never hurts to be always ahead.
In the situation mentioned above, how can we be ready, given that we cannot prevent ourselves being lost there? Bring extra, of course! If it is a long trip, bring a lot of extra batteries as you may never know what may happen.
If it happens, though, that there are no cell sites nearby (let's say that what you have is a mobile phone)--let us sace it for another time.
All UPSable
