I don’t think of it as normal or abnormal not to drink coffee. What is normal, anyway?
Many people drink coffee. It’s helps with concentration, helps people wake up and be productive, and it is nice pick me up when you’re out with friends. Tea is very popular now, too. All kinds of teas for all kinds of tastes and needs. Teas for taste, teas for waking up, teas for bed time, teas for digestive issues, teas for all kinds of health issues.
There’s nothing wrong with not drinking coffee. I don’t really drink wine and I rarely, if ever, drink beer. That’s not typical, either, but I don’t think twice about the fact that the world is full of wine drinkers and beer drinkers and yet I’m not one of them.
