Luckily I caught wind of two documentaries that were showing on TV and actually recalled that they were on today. I first watched "Six Degrees Could Change the World" about global warming and how life on this globe would change with each rise in temperature of 1 degree. Both shocking as well as informative.
A couple of minutes after that I tuned in for "What's the problem with nudity?", a documentary that runs a series of scientific tests in order to find out whether the all to often shame about naked bodies is inherited, part of our genes or something we grow up with depending on the society we live in.
Unless I totally missed the point, it seems the conclusion is that we are naked (as in not really having fur opposed to many mammals) because our skin acts as a gigantic cooling unit for our brain. On the other hand, we clothe ourselves because nudity is linked to sex and being tempted by nudity could lead to partners splitting up before their offspring (kids in normal terms) is raised to a level where they can stand on their own feet.
You can watch the program at the site of the BBC, but only if you are browsing from the UK (or find a way to make them believe you are there) : "What's the problem with nudity?".
