It is fun to imagine a person travel through a million years in a day. Well...not exactly what it literally means. The author brought the readers through an ordinary Saturday and talked about how those rituals or culture developed through all these years.
It is fun to see how similar yet so different we are from our ancestors. The author used humorous way to bring the readers with him to witness all those developments. I appreciate much the creativity and courage our ancestors had that bring such comfort and advanced lives we are having.
