Early Drinking Significantly Raises Dependency Risk In Later Years

Here we have another "study" from the no-shit-Sherlock department. Why can't I get funding for some of these no-brainers?

If a person starts drinking alcohol before 14 years of age he/she is at a 78% higher risk of having an alcohol problem in later years compared with people who start when they are at least 21, say researchers from Boston University School of Public Health, USA.

How much did they have to spend to figure out that? Of course if someone starts any bad habit early, it is more likely to persist; haven't these people got any contact with the real world?
