I think that's not because of alcohol - I am a light drinker (3 a week, or less) now and it's because my life is better and I am healthier and not as stressed or poor. I can drink not daily because I'm not an addictive sort of person. Yeah my health is better now than the years I didn't drink but it's because I have more money, can get medical care, have time to exercise too, all the benefits of the easier lifestyle we finally reached.
I don't think it's so harmful, nor helpful, always take July & December as dry months and see no difference in how I feel.
I know that's anecdotal, but unless they are controlling for income and overall lifestyle, my guess is that light drinking is an indication of a healthy moderate sort of lifestyle not an actual healthy factor in one.
If you don't count investing.
$2, on a lottery ticket; most I have won is $78. Overall have at least broken even, i think, I don't buy them often, just once had a winning streak of $2, $5, $20, then the $78, all on the same numbers that came from a fortune in fortune cookie I got twice in a row in two different cities that said
"Battle the enemy as long as there is life."
If you count investing, 17k, my 401k was halved in a crash at the same time I was laid off from my first real job.
