Has anyone heard of the exercise machine, "The Gazelle"?



Answers:
It's blue when it stays on the inside, where it obviously should be. Take a look at the veins in your arms (cause their easiest to see)- it's not you veins that are blue- it's the color of the blood running through them. Blood only turns red when it hits the oxygen in our surrounding air, becoming oxidized- the oxygen in your body isn't enough to do it.
