I completely agree. I know has been a chart out for sex & weight that tells you, but that doesn't even take into effect your tolerance.

Unfortunately they will never have it. If one drink meant you are buzzed then they can get you on that though you are not in the slightest bit impared.

There is also driving when you are tired, which is just as bad or worse depending on how tired you are. But people do that all the time too. When does it end?

Here in my county there is not a public system of trains or subways. We have to rely on cabs, and can you find a cab at 2 am? Normally you have to wait at least a half hour to get one at that time of night.
