I get that advice. I'm not a constant heavy drinker, and I'm not looking for a magical hangover cure because I frequently get shitfaced. Short of abstaining from alcohol altogether, I'm more interested in a supplement that combats the negative affects of alcohol on the system, because even a few drinks that doesn't cause hangover symptoms the next morning can still create toxins in our body. And bringing this back to the longevity topic of the thread, I want to continue to enjoy beer and wine as I get older, and if there's a supplement that will mitigate the adverse effects of that on my body, I'm interested.
And, we consume a lot of other things that aren't good for us, even things that we know are linked to higher cancer rates. BBQ, for example. There's a good amount of literature talking about how the process for smoking meats creates carcinogens. And red fatty meat in general is not as good as other leaner healthier meats. But I love BBQ, and I'm not going to quit eating it. But I don't eat it every week.
