A few years back, maybe around 10 years ago, I wrote an essay about how would our future would be if we continue to pollute our surrounding. I thing I remembered most is when I said that time would come that our air is so polluted that clean oxygen would be available in bottles.
To my surprise, air in can is now a reality. I don’t believe that our air is that polluted that it warrants a need for this product. As per advertisement, the product is more of medicinal in purpose rather than necessity.
