Alcohol is really, really bad for people, isn't it?

I see quite a few people who drank a lot when they were young
becoming like living corpses once they pass 50.
Even those who claim to have a high tolerance
can have their complexion change in an instant.
Please don't drink too much just because you feel healthy when you're young.
It gets difficult starting from middle age.
It feels like alcohol is slowly paralyzing the brain.
