Shower Products for Men

I was randomly surfing youtube when I chanced upon this testosterone-filled, ultra masculine video advertising shower products for men. Personally, I felt that there are many not-so-subtle messages embedded within the video about gender stereotypes. It also pokes fun at some of the products currently on the market for men: cue the Lightspeed 3000! I have always wondered why the new razors that appear on the market have increasing number of blades with finer blades within blades and finest blades within the finer blades blah blah. Do we really need that many blades that essentially perform the same functions? Or is it just more masculine and manly to have more and thus the products sell better? What are your thoughts?
