I have worked in and around some dangerous environments: foundry, machine shop, plastic extrusion lines, chemical refinery. I would never come back to work buzzed. Back in the 70's, when my job kept me in an office, I would have a margarita at lunch if we went out for Mexican or a beer if we went to the chili parlor. At some point in the early 80's, I stopped drinking and when I resumed 17 years later, drinking at lunch was out of fashion.
I enjoy a couple beers or a couple glasses of wine with lunch on weekends and when traveling for leisure. But as I get older, I find it leads to an afternoon nap if I don't get moving and stay active as soon as I get up from the table.
