I used to be in to electronics and electrical experiments as a hobby as a teenager. I used to build the sound to light units, which were pretty simple back then. As the years went by, and microchips became more and more complex, I stopped making such advanced controllers. I used to make my own PCB's, but when the larger microchips came out, that required multi-layered PCB's, they required more testing and "soaking" as in checking out fully.
I always remember when satellite TV came out, in Town shops - people started stealing the Astra Dishes. So, I went one better and made an alarm which was continually scanning from the dish to the LMB single line. Many friends asked what the black box on the wall outside was doing, it looked like the front part of Knight Rider's car "KITT", with 10 LED's scanning for movement or tampering to the dish. I actually made a few and sold them, did not make much on them because parts were so cheap to buy, if you knew what you were doing.
We used to have great times playing in the parks, over-grown bushes and large ponds in fields, climbing trees, etc. Now it is against the law to even climb a tree!! We used to play "British Bulldog", where one person had to tag another, we even done it at school - but trust me, I ran straight into one of those old massive round school bins on three wheels, bent my wrist back that far I fractured it, and it was my left hand - course teachers knew I was right handed, so I couldn't pull that stunt either! lol
Those were the good old days, no mobiles all we had was watches which our parents made sure we took with us, so we were always back on time, or grounded if we were late!
Then look at today, take away the internet - and all kids wouldn't know what to do with themselves. Even now, my daughter comes up to me and says "I'm bored", she's got a mobile, tablet and computer! 
My eldestt son just before Christmas last year, okay last month! Went for an interview, he was sick of Retail work, and it was part-time. So, attended an interview with a massive UK company. One of the questions they asked him was this "Do you have a Facebook Account?", he thought that's a strange question to ask him, they even as far as to ask him why - he said something along the lines of, well for a start it's all drama - and why would he want to know what other people were doing when he had his own life, he even said it makes people so anti-social, which what this society really is. They were so glad by his response, he won both interviewers over and got the job, full time and decent pay, company car and bonuses.
There many reasons for not having Facebook accounts, or if you do make sure it is private. Facebook recently applied for a patent on a new technology, and it is probably one of the most obtrusive ways to your privacy of you and your friends. Basically, in the future when a credit check is done on a person, it takes in to account the people you are friends with, and if they have low credit score then affects yours!! I couldn't believe that just one bad report on a friend on your friends list could stop you getting a mortgage, car, etc....
Today's world leaves a lot to be desired...
