Nice post and we are in the computer age and we are able to invent many different and wonderful techonology that are useful and they can be expensive as well. There are interesting apps like how to track one another through the app, one will know if she will go to a restaurant, if she will get a taxi, or if she will go to the market. She can track her bf if he has another girl, and he can track her if she has other boys. It's a fun app and maybe me and my boyfriend can have this app. One has to ask permission before it is approved.
It sounds scary to me these apps but they exist for at least 15 years or longer. Each mobile phone can be traced. Batteries can no longer be removed. Not only your partner but police, governments, google use it too.
We are forced into this technology and now we are addicted. Wait till the power is switched off.
