Crazy world we 're living in , i tend to be paranoid , maybe because i come from a computing master degree , or maybe because i simply know the world we're living in ,i deactivate everything on smart phone , unistall everything , only use minimal stuff ....same on computer , but i also know it's not sufficient so i simply control what infos can be seen ..... commercial use of information is the head of the iceberg , social engineering and population manipulation is another one area that sounds like a old 80 'movie but true , security agencies profiling ect .... again nothing dangerous until it comes dangerous and then , not escape ....
I remeber how i laughted when people we're exited to get finger print sensor on smartphones lol or eye reconnaisance on computers .... just waiting for the blood dna collection to close the circle ....
