6 Pack Large Portable Canned Oxygen Flavorless Original with 200+ Inhalations (for Everyday use)

Best of an oxygen product offered by any seller on this site!

There's an otherworldly feel to these flavored oxygen canisters. Earth has 21% native oxygen so why do earthlings need more? Go back in time 65 million years when dinosaurs roamed our planet and let's find out. Oh yes, the Earth was one giant jungle and trees were out of control.Why? Because the previous era produced way too much carbon dioxide which then promoted out-of-control tree growth (trees LOVE CO2) which promoted huge herbivores to eat all that vegetation which begat enormous carnivores to eat those herbivores all the while those trees began producing too much O2, so much so that insects, which do not have lungs and struggle (today) to get enough needed oxygen through their skin, got so much that dragonflies grew to be the size of condors (see the movie Caveman with Ringo Starr)!Anyway, these SWAG canisters make me feel like a powerful prehistoric dragonfly when I'm struggling for enough oxygen after a vigorous workout. I also take several inhalations before bedtime to promote better sleep and hopefully less snoring (not sure the latter is true because no one around to verify it but it makes some sense).I do wish in the future that SWAG would deliver the 6 canisters without 6 individual plastic breathing masks but provide one higher-quality, better-fitting multi-use mask instead. Other than that, an amazing product perfectly fit for our current Cenozoic geological period!
