It is said you not only need to keep food at least 30-100 meters away from the tent, which is easy do to, but you also can't sleep in the same clothing which was worn while eating, which can be very problematic or impossible to follow if you make a mistake.
I am concerned about European brown bears. See my earlier question.
Let's say hiking in relatively warm weather in only shorts and T-shirt. Cooked in that clothing. Do I have to undress to being naked and put on another T-shirt and shorts to sleep in? What if I only have 2 pairs and mix them up, forget to change in the morning and eat breakfast in the sleeping clothing, and suddenly I am left with no spare clothing which I haven't eaten in, so I must sleep nude or become bears breakfast myself?
What if I have underwear, does that need to be changed too and keep cooking and non-cooking underpants?
It's so easy to mess this separate clothing thing up, I can never tell used clothing from clean, always mix them up and forget to keep clean in the clean bag and dirty in the dirty bag, never can manage to keep them apart. What if during changing the cooking-clothes will touch the non-cooking clothes and suddenly both are contaminated?
Do you use your cooking clothes only for cooking, and hike in the non-cooking clothing? This would require getting naked before and after eating. Not very practical, and not very pleasant especially in colder temperatures.
Even if the clothing is managed perfectly, still my breath can smell like food, so does this clothing changing thing even make sense?
