Sometimes it’s interesting to see just how much our world has changed and is changing. Back in 2000, I researched the topic at the local library for a presentation for the local school – “The Sum of Mankind’s Knowledge”. At that time, the total sum of mankind’s knowledge DOUBLED every 7 years. Take a look at this video if you have 6 minutes to spare. It demonstrates just how rapidly our culture is changing. Like it or not, we can either go with the flow or try to swim upstream.
