Can you believe that 200 years ago people believed that if the train travels faster then 40 miles/hour that the passengers would suffocate ?

Can you believe that we used to measure our economic strength by how many slaves one would own?
 
Now Imagine it is year 2210 and people are looking back 200 years and taking apart our world and our believe system. They may say something like this;

Can you believe that they used to believe that the war would solve problems? Hahaha

Or  “ can you believe that they used fossil fuel as a main source of energy ? LOL

Here is one that just popped into my head. Can you believe that people in 2010 would do jobs that they did not enjoy doing for decades just to get a paycheck? Uhhh that would hurt.

Send me a comment if you can think of a belief we posses right now that will be obsolete 200 years from now.
