moustaches have different cultural associations like for 20th century arab countries they are associated with power. Beards in islamic traditionalism and lackof facial hair is associated with more liberal secular tendencies.
I had noticed that while watching the news, but it is nice to know that it wasn't just in my head. I remember when it meant you were a hippy.
it has many different purposes. in islam trimming the moustache is considered to be "sunnah" and "mustahabb" which means a way of life that is recommended especially amont sunni muslims!
I know that in rural areas in the US it was a way of keeping warm when doing farm work in the winter. My dad always had facial hair in the winter.
yup. is has been with us for a long time and we know because there are moustaches depicted in several acient art forms. for example a statue of 4th dynasty egyption prince rhotep has a mustache :)
I have read some new studies that say humans are getting less hair as we evolve. No genetic need for anymore I guess.
interesting, we have also been shaving for a while. shaving with stone razors was acually technologically possible from even neolithic times.
