People should shower regularly, but I find the aromas wafting from people who use many fragrance products far more offensive and offputting than someone smelling like a human. Some people's shampoo, laundry detergent and deodorant (not to mention body spray, cologne or perfume) are so strong that I can smell them from 5 feet away, and the odor lingers for several minutes after they leave an area. I don't really care what it smells like as much as that I seem to be allergic to these fragrances, and sneeze, get red eyes, my nose starts running my lips swell a bit. This is why some places have instituted a fragrance-free policy - as many as 25% of people have an allergy to various components of these perfumes. Unfortunately it's a very touchy thing to explain to people as the average person thinks they're doing something virtuous by wearing a bunch of fragrances and it makes them more appealing to be around.
