that is DEAD on for me.....no difference at all.....i might be freezing....or have a real bad itch, and have to cough at the same time.....you know the type of feeling where your throat almost itches.....i could be right on the brink of letting off a big ole cough and then if i see a deer in sight......BAM, everything is focused on that deer.....honestly i dont even know if im breathing for that first minute or two when he comes into sight!! its a great feeling.
