You do have a point akhi - it is indeed a torture to see the typical YT page. May be we can make a polite suggestion to YT to build an option in which nasty things are not visible and only links and short description appear. Coming to the video in question - this is great. It is strange how your affection builds up even for the speaker. This is the advantage of focusing on the positive things. Though it is tiring to keep reading a narration in which significant ideas are flowing at a considerable rate but it is worth it. Wassalam
