The sunlight is the energy used to convert the nutrients to sugar.

Oxygen is carried to the cornea by vitamin B2. The surface of the skin gets its oxygen by the same process.

Booze destroys B2, so arteries grow into the cornea, causing bloodshot eyes, and into the surface of the skin, causing red cheeks and red nose. Some ethnicities have a genetic predisposition to B vitamin deficiencies, and that is why they are famous for their red noses.

Vitamin B2 is a water soluble dye that makes the urine bright yellow. When the color fades, it's time to get a supplement.

Do you hear that ladies?  Looking for a husband, go to China.  

Yes, and they also cant give a scientific explanation for yawning either. ;O

If you did both in the same night, would they sneeze be the peaking moment and the yawn come afterward?  Or would it be the other way around??

  

And not always then

Not quite only: so do bonobos.
