Phenomena? Hey all! Since I have gotten into cycling I have seriously noticed my olfactory senses are in freakin' werewolf mode! ha! At least while I am riding. For some reason, after an hour or so on the bike I pick up on the craziest scents...I first realized it when a Jeep passed me one day and I smelled the gal drivers' perfume for what seemed like 5 minutes as I cruised along after...and was all like "holy sh-t!" I usually smell a commuters cigarette forever, peoples laundry dryer vents, and if someone is cooking out some crazy distance away, fuggetabout it- feels like I am all up in their GRILL! haha! I guess the combination of my lungs expanding and contracting so rapidly, heavier breathing mixed with the fact that I am much more at peace and in touch with things out there while on the bike???? Paying attention when I normally wouldn't...perhaps.
