Yep sure a lot of wise old men have passed from this world. They lived and learned what they knew first hand. Some shared that wisdom with others. Unfortunately, as I have stated many times before, so many today think they are smarter and much more sophisticated and can avoid such difficulties and will not heed the advice of those wise old sages. One only needs to look and study history to understand than nothing is new when it comes to human nature and the cycle continues as later generations forget and fail to learn from those who went before. The answer to the future lies in the results of the past.
