Earlier quoted context omitted.
If you live that same life and drink a glass of grape juice instead of wine everyday, you'll live even longer. Alcohol is a poisson and there is no "safe" level. Now, it's a personal decision how much risk is acceptable to you, but don't lie to yourself how "one glass a day is not going to make a difference".
This is a very uneducated comment, considering available research. While some doubt can be cast on the J-shaped curve, we have a lot of evidence for all-cause mortality either decreasing or at least not increasing with low levels of consumption.
Industry funded studies told us smoking was safe for a long time. In the case of alcohol we absolutely know that high doses are very dangerous. There are lies, damn lies, and statistics, after all.
Maybe there's a safe dose of alcohol. Maybe the risk of low doses is small enough to be accepted. But we've been lied to buy poison vendors enough times that I'll take any of their proclamations of safety with a mountain of salt.
