To Breathe or Not to Breathe
How long can you hold your breath? 10 seconds? 30 seconds? 400 years? Breathing is both voluntary and involuntary. This means that you can control it if you want to. However, just in case you forget, your brain will take over and breathe for you, allowing you to concentrate on other things. If you hold your breath for too long, your brain will kick in and force you to breathe.
If your body cannot breathe, your cells will not get the oxygen they need. If this happens, your cells will quickly begin to die. Within only a few minutes from the time that you are not able to get breath, your body will die. That is how important breathing is.
