> We can see lots of useful examples of a protective social norms with alcohol. For example, it’s quite common for people to not drink any alcohol before a certain hour of the day. It’s not illegal to drink alcohol earlier, but it’s “just not done”. I find this point quite interesting. I didn't drink alcohol until I was nearly 30. I skipped by most of the formative alcohol consumption experiences most people have. And, incidentally, I don't seem to follow the same norms about what time of day it's okay to drink: I'll happily have a beer well before noon.
