Interesting video, thanks for sharing. However i do not agree that Michael Collins was or has been the most loneliest person on earth. There is a difference between loneliness and solitude. Solitude is when you are alone, this is something that is objective, and has nothing to do with how anyone feels. Loneliness is the subjective counterpart, if you feel lonely, you are lonely, period. Hence why you can be lonely in crowds and such.
Sorry for the ramblings, i know that probably wasn't the point of your post, but oh well. Anyway as i said i really liked the video, will check out more of him.
