Personal hygiene, a lost art?

I cannot tell you how many coworkers i have come across in the last week or two that stink like they haven't showered in days/ate 4 bulbs of garlic/shit in their pants. What is going on? Sure, people eat stinky foods, sometimes have to fart, etc., but the stench i have experienced is so bad it makes your eyes water and/or children weep. Oh the humanity....
