Going to practice drunk is stupid and should not be confused with relaxing and having a few drinks 1 night a week or every other week outside of the competition portion of the season.
Not that you need a study to find this one out, but drinking has also been correlated well with sexual activity. Not suggesting you change your life for the purpose of drinking like some people do in college, but you’re going to have a hard time going to college parties and enjoying yourself completely sober all the time. Drunk + laid on occasion > sober + hand all the time.
