Time is weird, and clocks are all around us because of our relationship to time, calendars, that allow social meetings.

Today we got a historical gem on YouTube: the history of Big Ben. Many many men (women seem not to exist) have been involved in this UK project: all for a tower, a broken bell, and zillions of photographs taken by tourists ….. of a CLOCK.

Should we give birth to other humans so that they too can have a life time? Should we allow ourselves to waste time if such a thing exists? Are these considerations important?
