I recall when cell-phones were announced the very first time. I have to confess that I was still quite young and foolish at that stage and did not quite understand what the fuss was about. Buddies of mine had a cord-less phone and I was under the impression that this cool telephone was in real fact the same as a cell-phone. I still remember one of the headlines in a newspaper where they were advertising the arrival of the cell-phone: You'll be able to phone from your shopping trolley in the grocery store! At that stage it was quite a novelty, however these days even the beggar on the street corner has access to a cell-phone and also to the frustrating "please call me" function that goes with it.
As frustrating and bothersome as cell-phones may be, they also play a major safety role in our lives. Visualize being stuck without petroleum next to the road - you don't need to stress, just grab your cell-phone and help will be on its way. For those who have young children it is also a good way to quickly get hold of them. just to make sure if they are still okay and if they're actually behaving.
A number of other "nice to have" items might also contribute to not only our overall ease, but in addition to our safety! If we have automated gates or garage doors we do not have to climb out of our vehicles when we arrive home in the evening - we just press the key on our remote control, wait for the gate and garage door to open, drive in, push the button and there you are! Safe and secure. On a rainy day this is certainly even more pleasant, as we do not end up soaking wet while attempting to unlock our gates!
