On the other hand if you were unpopular or unfit your "fun" and activity options were a lot more limited. Just saying i have quite some experience of being a child in a tech free country (comunism made sure we lived the 70s in the 80s and so on) and if you were not a popular kid it was far from the pretty picture you portray. At least nowdays kids don't pick on other kids for doing anything tech related or for talking about star wars and star trek and gamer isn't a dirty insult anymore (in the 90s in my school the rank went gay<gamer<loser<chump<nobody<cool<popular).
Tell you what I'd change a large part of my childhood for the childhood they have now, and don't worry even though I spent a lot of time with books and not roaming the streets I didn't get fat and I'm 33 and still keep in touch with my best friend that i met at 12years of age.
Your mileage may vary.
