Step-by-step explanation:

Answer 2

I can exercise if the last time I ate food was 3 days ago. I can’t exercise if the last time I took a breath was 3 days ago. You need it or else you will pass out. I cannot even exercise vigorously if I stop breathing for a minute. My body will need oxygen and I will faint. You need to keep breathing at all times.
