An excellent reflection. I can draw a small parallel with my experience with tobacco. As I was always told it was bad for my health, I think puberty always brings something stupid and not very evolutionarily intelligent, but that's part of it, isn't it?
With regard to alcohol, I think my first drink must have been around the age of 17... at the time, it was at a café-concert that we organized to raise funds to set up a group of young people with the capacity to throw parties, attract more and more people, and hire musical groups. I was at the entrance, and I was one of the people responsible for collecting the money and exchanging it for tickets, which would then be used to buy the drinks and food. Of course, it goes without saying that many of my friends offered me tickets.... and at the end of the night, they were exchanged for drinks that I wouldn't even dare to drink today: Golden Strike, Pissang Ambom, and other sweet liquors.
I can say that my qause daily one-hour addiction might be my workout at the gym. Although I can't go every day, I go at least five times a week!
Make the most of your vacation days in Estonia to relax... It feels really good!
