Earlier today I tried a simple form for 10 minutes : sit straight up , close your eyes , and pay close attention to every breath . The first couple of minutes felt like an eternity ; I was n't sure I would last for ten . It felt like my heart was beating too fast or too hard ; it was pretty uncomfortable .

Question: Why was the narrator focusing on their breath ?
Answer: None of the above choices .They were afraid .They were running for their life .They were exercising .
