Should there be an age limit on drinking?

Yes, young kids shouldn't be able to drink because their maturity level is not even high enough to act as a grown adult sober. Why would we want drunk kids running around everywhere, acting like drunk kids? Maybe this is why we have so many don' tdrink and drive commercials?? Coincidence? I think not. Adults can't even handle drinking maturly, why should we trust younger ones to?
