I'm having a nice relaxing bath and I start wondering how long I'd be able to hold my breath for underwater, so I prepare myself, block my nose and slowly sink underneath the water for a few seconds to try it out. That was relatively easy, so I decide to go ahead and practice holding my breath for longer. Taking a deep breath, I block my nose again and slide under, holding my breath for as long as I can. I come back up and catch my breath and decide to go once more to see if I can last even longer this time. Do you think I can make it?
