Which one do you choose?

I like this talk a lot. There are so may ways to enjoy yourself, to keep yourself during the breath hold indeed. I sometimes sing a song in my head. Or I very slowly spell names of animals or cities backwards. Or I visualize a funny scene with my dog ... when 'watching' her funny face watching me, asking me to play then I start to smile during my breath hold and I instantly relax. So many scenes we can play in our inner cinema 📽️🎬

When doing that final breath in the last 5 seconds before the dive Gert, does it matter if you take your breath through the mouth? Or is it also okay to breath in through the nose? Is there an important difference at that moment?
