blood circulation

[AwesomeRicky8]

thanx a lot gotta go study

[thetreeceman]

When will the "blue blood" myth die? We do not have blue blood, ever. The red and blue convention is used in diagrams to differentiate between oxygenated and deoxygenated blood. It is never actually blood. Before you try to tell me otherwise, just google it.

[thetreeceman]

@thetreeceman Never actually blue, I mean to say.  Blood is indeed actually blood.

I suffer from erectile disfunction. I heard that garlic tablets can help improve circulation as well as potassium rich foods and drinking 8 glasses of water a day. Does this help circulation?
