We will still be dependant on our phone in our 90's
What's happening now in real-time, is that the entire world has become wholly dependant on their phone and the internet.
It's handy for all sorts of reasons, like returning goods from Amazon without having to use a printer.
More so for a 90 year old because it would save them from having to go outside to buy big or small stuff, or to speak to other people.
I hardly look at my iphone at all, and only use it when I need to buy something over £300 more or less ..I cannot do that, until I get the one-stop pass codes from my bank sent to my phone, that I then have to type into my computer device or phone, where I am making the large purchase from.
Not addicted to my phone, but it is a compulsory item to have, if and when I ever want to buy anything online. Or speak to anyone online.
The phone and the internet is very useful. But hardly addictive, well not for me anyway.
