I don't believe there should be a legal drinking age. I quit heavy drinking when I turned 21. I started drinking beer at 21.

I joined the Army at 22 and didn't drink again until my team went to Iraq when I was 31. The entire team stayed drunk most of the tour. I'd go into Baghdad once or twice a week and come back to Al Hilla with an FMTV loaded with pallets of beer. We had walls of beer in our safe house. I went from 184lbs to 220lbs in less than a year.
