and what evidence is there that lowering the drinking age would make this more of a problem? european countries dont struggle with this kind of the thing the way america does, and the drinking age there is lower than here. unless you think europeans are just naturally smarter/more cautious than americans, the evidence seems to suggest that lowering the drinking age actually stops kids from drinking too much too fast like op did.
also, op said the only reason he drank the whole bottle at once was because he couldn't go in the stadium with it. presumably he was too young to drink and thus couldn't get passed security with the bottle. or the stadium just has that as a rule for everyone. either way, it was a rule banning alcohol that caused him to do what he did, not a rule that liberated him to drink as he pleased. presumably, had he been able to bring the drink into the stadium, he would have consumed it slower, and, thus, more safely.
