Well, it's because people like to look at history, contemporary history. The last 50 years, my recording life as a filmmaker. 19 fifties, 19 sixties, 19 seventies, 19 eighties, 19 nineties and some things from the present. I invite you to subscribe. Take a look at my channel, see some of these clips and comment. You won't be alone in the comments. I get thousands of comments a day. Very interesting responses from people. Positive. Negative. Take a look at my channel on YouTube. I think you'll find it entertaining, provocative and the comments off the charts. Thank you.
