One of the benefits of being retired is that there's almost no limit to my "free time". So this afternoon, having nothing better to do I spent some time on YouTube. You know how it is on YouTube. One video leads to another which leads to.... Well, you get the idea.
While perusing the mundane videos I came across this one and I must say, it's among the most interesting videos I've ever seen. It's almost 42 minutes long so when you sit down to view it, make yourself comfy, grab a cup of joe and enjoy it.
