No, I dont think the drinking age should be lowered to 18 or 19. I do think that the whole level of adult-hood should be raised to 21. These days, I dont know of a lot of 18 yr olds that have moved away from home & are able to stand on their own. dont get me wrong, i dont think it's strictly a maturity-level deal. I think the economy has a lot to do with it as well. But on the maturity level, I also dont think the 18 yr olds of today are as mature as they were 20 yrs ago.
I know this is going to P.O. a lot of the younger crowd, but that's just what I see with my own eyes...and maybe the fact that in my line of work I am seeing the first generation of crack-babies that are growing up.
