Strange as it may sound, I found that fascinating. We *can* learn from the past, after all. ;)

Glad you enjoyed it. Humans have figured out some pretty interesting things, just some of the good stuff gets left behind in search of the "new" and "improved". It's good to see some old knowledge being rediscovered, and hopefully used in the present :)
