Just like your doctor, my liquid intake is just water. Water is life and nothing can be healthier than it.
Talking about taking alcohol, yesterday I was at a neighbor's birthday ceremony and of course there was beer there and malt drinks. When I was offered one I said I'd prefer water to any of them. The guy serving asked me why I don't take any of that and I said they aren't good for the health. You should have seen the way they all laughed at me and engaged me in a talk on the benefits of taking beer.
The celebrant said it helps to calm the nerves and relaxes the brain after the day's stress.
I didn't bother replying them any further because nothing can make them stop.
