50 Obsolete Things To Show Just How Much The World Has Changed (New Pics)

Nostalgia brings things back. It stimulates memories of the times when we were accepted and loved and this phenomenon is very comforting. Knowing that at some point in life we didn't have to earn our love can be very powerful. Nostalgia helps us realize that our parents, our siblings, or our friends simply loved us unconditionally. And these thoughts can work miracles on us when we're undergoing turmoil in our personal lives.

Batcho believes nostalgia might even have an element of infectiousness and wishes it was even bigger. To understand what she means by that, think of a group of people who have some shared experience.

"The best example of that is when a group of friends are reminiscing about their antics, the things they did as either teenagers or children or what have you. There it's a bonding experience. Another example of that is we know from current research that sports fans love to do that. They talk about the games that they enjoyed and when their team was victorious. When you have a common bond, it can be very infectious and it's like a domino one memory triggers another."

And the reason why she wishes it was more infectious is that this, let's call it, collective nostalgia can break down when you have a group of people who do not have shared experiences to be nostalgic about. Suddenly if you have one individual wanting to reminisce about their past but no one else in that group remembers those things or lived through those things, you might get things like a generation gap. Someone is talking about the 1950s and a teen says they can't even imagine it.

So when you think about it, r/Nostalgia is doing a beautiful public service. The subreddit is bringing together those who might not have anyone to daydream about the past with.
