Can you mix drinking and exercise?

The timbre of your definition of "healthy life" sounds quite like rigid religious orthodoxy. Try "I don't get the pairing of being Catholic and having premarital sex. I know someone that goes to church every Sunday, but..."
See, in the case that she's trying to be a "good Catholic" or "healthy liver", it comes across as judgmental and priggish; in the case that she's not particularly concerned with what others think of her devotion, it comes across as dogmatic and parochial.
Anyway,"a healthy life" would be defined by many people as whatever mix of healthy activity and hedonistic enjoyment best suits the individual's well-being, including their psychological well-being. For instance, I have a friend who has cancer and is going through the torture of the damned with chemo. Yet above all, he's utterly miserable that he's not allowed to eat anything besides vegetables; the once-a-month Big Mac keeps him going and gives him something to look forward to.
I don't even like when doctors do this, but unless you're her doctor, you should refrain from casting judgment.
I think for a growing number of people that alternative is non-smoking forms of cannabis. I grant you it isn't a 1:1 substitution for everything alcohol, but it's a lot safer to use and still a very social experience. I suspect that at some point there will be a "synthohol" like substance, but who knows when that might come about.
Just about when the individual is entirely castrated à la Brave New World, and everyone worships health as part of their commitment to a perfectly harmonious social organism. Luckily, this will never happen - rebellious people in some godforsaken country will always find a way to give each other hangovers, as a simple Darwinian test that involves the ability to hold liquor while saying something interesting. And that country will end up more innovative than the ones that sank their population into some opioid or another as an expedient to having a healthy body and a numbed-out mind.
We do; it's called GHB.
However, once the hangover has arrived (the next day), a run can do wonders.
As far as non-dangerous exercise, such as gym cycling stations, or a Bar-group-pedal-cycle guided exercise event, I think there's a possibility that drinking and exercising might just possibly have health benefits--pure speculation though; it would be interesting to test and do studies on this topic.
