Eeeeooo, Red Bull. Is there anything natural in that at all - even water? I'd never touch the stuff but my girlfriend is still capable of using it as a mixer and downing several, which I cannot believe is healthy at all. You're storing up trouble for the future, young nights!
[Breadmaster] Red Bull contains taurine, which was originally extracted from cattle. (Hence the name. The myth that it came from bulls' testicles is just that - a myth. The substance is found all over the body.) These days it's synthetic.
Red Bull has its uses - ie when you're at the far end of the M6, and home and bed are at the southern end of the M40. But yes, it does taste revolting, and I can almost feel it dissolving my teeth as I drink it
