Even if you don't technically become an alcoholic, getting drunk once a week for decades will absolutely have ill effects on your body. This is medically inevitable.

It should also be a person's choice. I find this the main issue. Personal freedom. Many people choose to drive a car, which has one of the highest mortality rates. But people still drive. What's wrong with a drink or a smoke then, even if that person knows it's dangerous.

Where do you get your information?

Yes but those people aren't exactly drinking just a little to become more productive the rest of the week. It's quite likely their day jobs are the hourly type factory based where intellect is need not apply.

I think the comment i was replying to stated that a little relaxation in the middle of a stressful hour can really help you focus more.
