dead space
dead space is air that is inhaled by the body in breathing, but does not take part in gas exchange. Not all the air in each breath is able to be used for the exchange of oxygen and carbon dioxide. About a third of every resting breath is exhaled exactly as it came into the body. In adults, it is usually in the range of 150 mL.1 Because of dead space, taking deep breaths more slowly (e.g. ten 500 mL breaths per minute) is more effective than taking shallow breaths quickly (e.g. twenty 250 mL breaths per minute). Although the amount of gas per minute is the same (5 L/min), a large proportion of the shallow breaths is dead space, and does not allow oxygen to get into the blood.
The Urban Dictionary Mug
My dad hated it🤣

This is the coolest Anspaugh mug that ever existed.
Great ordering experience..good quality

The day this mug entered my life, my depression was cured, I won the lottery, my dad came back from the dead, and my mum started loving me, motto beg but if you rub the mug 3 times a genie WIll grant you 69 wishes (I wished for more mugs 69 times)
Gift for my niece. She loves it.

Describes my classmate in school, perfect

*To those looking to purchase, others may criticize your sense of humor.* I love the thug shaker mug! It stands out as a quality desk ornament that all of my co workers are envious of. However, the other world leaders seem to find the thug shaker unfunny and immature for the work place. My wife says she will leave me if she sees it out one more time. I think I may have to give up the thug shaker persona once and for all. Stay strong thugs.
fuck you and your mugs give me a shirt or ill shit on you
Love love love it! Customer service gave me a coupon, let me know that I had to revise the definition when too long, and overall super helpful.

Nice Mug my second Mug. A little staining or photo graphic stain on the side of the cup and shown in the picture. As a result I cannot give a 5 Star Review.
The snarky message on the mug always gets big laughs from guests so I'm now using it as my go-to bourbon glass
Love the coffee mug. Would have been nice to see who had the word accepted into Urban Dictionary printed on the bottom of the mug. As I was the one. "Dusty Dawg" Other than that I love.
fuck ur mugs i want one for free
