When I did the Appalachian Trail in 96' (2,164 mi/3482 km) my daughter picked me up for a few days as she was at VaTech near the AT. The first thing she said when I got into her car was "Dad, you stink! I am not going to bring you to my apt smelling like that!"
So, we went directly to the laundromat and I SUPER washed all my gear...pack included. I looked silly sitting in public with her snuggy boots on and a fluffy Hokie Robe. She meant it...ALL my gear.
Gear now washed, we returned to her apt and some of her roommates were there. I was introduced and they were kinda nice, though a bit withdrawn.
Earlier, my daughter brought a pillow and a blanket out so I could sleep on the couch...where the TV was.
It wasn't long before my daughter said, "Sorry Dad, the others say you still stink. Would you mind sleeping outside on the balcony?"
I think if I could have gotten to the second rerun of "Three's Company" their
Olfactory fatigue, also known as
odor fatigue or
olfactory adaptation, could have set in. This is the temporary, normal inability to distinguish a particular
odor after a prolonged exposure to that airborne compound. For example, when entering a restaurant initially the odor of food is often perceived as being very strong, but after time the awareness of the
odor normally fades to the point where the smell is not perceptible or is much weaker.
Moral to the story: Prolonged walking can leave you in the pits and out in the cold.
