Taking a breath is not universalizable, because some people currently happen to swimming and would drown.
Actually, swimming is not universalizable, not everyone knows how to swim or can swim so making everyone swim would cause them to drown
Ah but you see I'm not just eating nuts
I'm eating nuts unless I have nuts allergies
I honestly Kant believe I had to learn about this dumbass.

Therefore anyone who can safely eat nuts has a moral obligation to do so. q.e.d.
