Can confirm. I grew up in the Carribean and I was allowed to drink beer and wine at a very young age. My mother taught me how to drink. I was definitely prepubescent, which is important because I hit puberty at ten. She explained that drinking can make you feel sick and that if I felt my nose feel funny I needed to stop and drink water.

Binge drinking and being fall down drunk is seen a something stupid, embarrassing, and something that only alcoholics do. I still find it strange and embarrassing when I see people racing to unconsciousness. What is the point of being blackout drunk before 9:00pm? We used to party until the sun came out, then we'd get breakfast and go to bed.

What the fuck? Prohibition until 21 keeps developing brains from being damaged

In a recent editorial in The BMJ, a trio of scientists pointed out that there are three periods in life when the brain goes through major changes and is particularly vulnerable to the effects of alcohol. Two of those periods are at the beginning and end of life. When pregnant women drink alcohol, it can damage the developing brain of the fetus, leading to physical problems, learning disabilities, and behavioral problems. When people over the age of 65 drink alcohol, it can worsen declines in brain function that happen during aging.

The third period is adolescence. During those years of transition between childhood and adulthood, the brain grows and changes in many important ways that are crucial for that transition to be successful. When teens and young adults drink alcohol, it can interfere with that process of brain development in ways that affect the rest of their lives.
