The world changes, it has always done so. You can go with it, ignore it or go for a mix of both. Forums like this one, for like minded people, have helped many a lonely person, on the other hand, buying online has created waste lands of once thriving town centres.
For my part, I have never seen Facebook and it's ilk, never bought anything online, although I have done so by phone and I still put my finger in the dial when making a phone call. Email is something that I have yet to master, but texting is a way of life. My so called smart phone is far to smart for me, phone calls and texts are about my limit. Cash is still my preferred choice as a medium of expenditure, cards and electronic payments are profiled, Big Brother has no idea how much or what I have bought, this Christmas.
The world changes, how you deal with it is up to you.
