Years ago there was a guy that raced at one of the tracks I bracket raced at that drank whiskey from the time he got there until he left. He told me it kept him sharp on the tree. I always paid attention to where he was in the lanes.
i know several guys who use to win a lot of money in bars betting about reaction times and the influence on them by drinking, a lot of money
They would have the victims, after several beers or drinks lay their arm on the bar and hold their thumb and index fingers apart about 3 inches and then take a 5, 10 or 20 dollar bill(what ever the bet was) out of their wallets and bet that the drinker couldn't catch it if they release it with the bottom of the bill held even with the top of the thumb and fingers
I can catch them when sober, after two beers or drinks not at all
