With the help of used-to-be military exclusive GPS or Global Positioning Satellites, any one can learn the exact location of where they are actually in. Anyone can tag him/herself on their location at any given time, and tell everyone about it through social media. If you are in China, you can tell everybody by using a smartphone. If you have traveled and arrived at the United Kingdom, you can shout to the world that you are there by activating your GPS, tag your location, and share it through social media. Basically where ever you are, you can tell everybody where you are in through this amazing geo-tagging feature of every smart phone that we have right now.
The main drawback of this feature is that if it is used too much, it can complicate some things. Some people will tend to use this feature too much, it can attract some unwanted personalities to draw in to your life. Even if you are in the outskirts of Scotland, any one can know once you have shared to social media. This is a concern for all of us as it can be used against us eventually.
GPS features can be tricky at times, so make sure use them with caution. Safe travels are happy travels!
