Here’s a very technical paper that studied nose vs mouth vs combined nose-and-mouth breathing:

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7455204/

I confess it was over my head and I just skimmed it. But the conclusion says, “The high filtration efficiency of the nasal cavity together with its efficient clearance mechanisms lead to the recommendation to prefer the nose breathing over combined or mouth breathing.”

The conclusion also says, “There is general scientific agreement that lower airways are more vulnerable to severe infections” and “From this point of view, the nasal inhalation is preferential because it significantly reduces the number of particles penetrating to lower airways.” I’d guess that means that shallow breaths are probably preferable, but you’d need to read the article to confirm that.

A kidney donated from a living donor often lasts longer and performs better than a kidney from a deceased donor. Donating a kidney to a stranger can begin a paired donation chain that can result in several people getting kidneys. If you are seriously thinking about donating, I strongly encourage you to do some research with reputable sources, talk to some people who’ve donated themselves, talk it over with your loved ones, and maybe talk to some transplant coordinators at the nearest transplant center. It’s not something to be undertaken lightly, but living donors are saints.

American here, and I’ve never heard anyone seriously answer the phone this way. I did have a co-worker who would answer “Go for Mike” as a joke when he knew the caller. I had the impression it was from silly comedy or sit-com or meme that went around for a while.
