Re: an experiment
Idk, i didnt know that not many people knew of that. As a tuba player, i was always working on keeping my lungs up to par by doing resistance breathing exercises everyday, and spending a few minutes taking in a breath and holding till you cant any longer, then breathe out, hold again till you are almost dieing, then breathe in again. And you repeat that a few times over. It prolly killed a few brain cells, but oh well. And, with the pop thing, i was just told this by one of my teachers, not really a credible source, but regardless, it prolly kept me a little healthier even if the effects of drinking carbonated beverages were temporary and minute.
And one other thing. Throughout my senior year of high school, i smoked hookah all the time, and saw no difference in lung capacity.
