They are talking about energy drinks and snopes got a direct link again, way to go snopes!
Rumors have swirled around Red Bull for years. Contrary to hearsay, the ingredient taurine (an amino acid important in making bile to aid digestion) is not made from bull urine, and Mateschitz did not learn about Red Bull from rickshaw drivers in Thailand. The urban legends-debunking Web site http://www.snopes.com has a page devoted to exposing the false claim that Red Bull contains a banned substance linked to brain tumors.
Crap! I've been preeminantly spanked! I was just coming to post my first snopes sighting!!
Anyhoo, they make reference to the fact that Red Bull was inspired by "tonics" in Asia. When I lived in Korea, such drinks abounded, and it was actually a national crisis because bus and taxi drivers were living on the stuff and causing accidents from unnoticed exhaustion.
The most evil energy drink available, and I'm sure it's still there, was made with ginseng and royal jelly. I watched a couple of my colleagues get hooked on that stuff, and it completely changed their personalities. Royal jelly is some awfully wicked stuff!!
They also had drinks with claims similar to today's chaser -- drink this and you won't be hung over in the morning. Basically nicotine and caffeine in liquid form. I was in a night club once on a Saturday night, and the bathroom attendant gave me a bottle of the stuff along with a "vitamin pill" (alright, I wasn't too bright in my early twenties). I was most certainly not hung over on Sunday morning, but I didn't sleep until Tuesday night!
