Do Not Operate Heavy Machinery

So I was wondering the other day about blood alcohol content(B.A.C.). As most of you know, in most states if you blow 0.08 or over, you will get a D.U.I. which will probably screw up your year and your rear. Since I know nothing about the science of it. This number seems confusing to me. I know it is a ratio, but I am pretty sure some people can have a 0.08 and do fine. Others not so much. Sort of like those that can drive and talk on the cell phone at the same time.

So, I pose this question. If alcohol slows your reaction time and this is what really causes accidents and such. Do you think it is possible, if you have a faster than normal/average reaction time, think along the lines of Barry Bonds, drag racer, motorcycle racer, etc that alcohol slows your reaction time to that of a normal human being? If so, should this make it okay for you B.A.C. to be higher? Or does this not even matter?

Please let me know what you guys think?
